Earlier this month, Morgan Cates of Camden graduated from high school. On Friday and Saturday, June 24 and 25, he will wrap up another journey that has taken almost as long to complete. “A Day in The Life: A Beatles Experience,” a multimedia tribute show written and directed by Cates, will be presented at the Camden Opera House, Elm Street/Route 1 at 7:30 p.m.

Beatles tribute shows may be rare in these parts, but they are a real industry in other parts of the country. “Beatlemania” made the first big splash with the concept in the 1970s; the latest Broadway Beatles show, “Rain,” won the 2011 Drama Desk Award. Cates, a musician and theater techie who blossomed into a singer and actor while at Camden Hills Regional High School, has drawn on this tradition as well as on the incredible rich catalog of songs produced by the most recognized band of all time to create his show, which runs about two and a half hours with intermission and features more than 25 Beatles songs.

Cates is a lifelong Beatles fan and his homage to the Fab Four is unabashed; he and his talented cast mates have no desire to give this music their own spin, and with good reason.

“We’ve spent five months rehearsing every night to replicate them as close as possible. I think it’s like classical music — you don’t change it because it’s great as it is,” he said.

A week-before rehearsal at Northport Music Theater, which is producing and is the beneficiary of the show, revealed how close to the mark “A Day in The Life” comes. Cates, who plays Paul McCartney, has a strong voice that is a fine, smooth fit on “Yesterday,” but he has learned how to let loose and howl on “Twist and Shout.” He also, in his bid for verisimilitude, has taught himself to play bass guitar with his left hand as McCartney does.

Cates is not the only one who has had to learn new skills for “A Day in The Life.” Alex Wilder, a Camden Hills junior, has the John Lennon dialect and speaking manner down pat and has worked just as hard at the music.

“Our John Lennon is a low bass who played three chords. We’ve stretched his range and he’s great on guitar now,” said Cates.

Thirty-one-year-old Ben Whitney, who plays George Harrison, is a crackerjack guitarist who nails the opening riff of “I Feel Fine” but, like his role model, has not been known as a vocalist — a reputation Cates thinks is misplaced in both cases. Whitney came to the project in a somewhat unusual way.

“He works at FMC with my dad, who came home one day and said I know a guy who’s great guitarist and likes to dress up on Halloween. I said, ‘he’s in,'” said Cates.

Andy Moore, the show’s Ringo, has a couple of decades on his band mates, years he has spent playing in a number of bands including current gig Rattleboxx. His performance experience and steady bea thas helped keep the exuberant show grounded as it wends its way towards the Camden Opera House stage for its two-nights-only fruition.

“I’ve known Andy a while and have worked on a number of projects with him,” said Cates, who credited makeup artist Terri Harper for “making us all look the same age and then aging us together.”

Costumes, makeup and character is nothing new to Cates who, as a first-time director, has had the challenge of giving that experience to his fellow band mates.

“I’ve been training musicians to be actors,” he said.

These four sing the songs and don the costumes and wigs, but there is a fifth musician on stage for “A Day in The Life.” Sam McKenna, a Camden Hills senior, lurks upstage with a couple of keyboards.

“The Beatles went into the studio and stopped performing live. They started working with 40-piece orchestras, which we of course can’t do,” said Cates.

McKenna’s contributions are surprisingly effective, from the strings of “Eleanor Rigby” to the “Sgt. Pepper” horn break. He also slips some bongos into the early numbers.

“A Day in the Life” is primarily music, although there is some stage banter between the musicians informed, Cates said, by YouTube-gleaned clips. Projected on a screen behind the band is vintage footage of both The Beatles and the tumultuous times they played in. Cates acquired the montage from Philadelphia-based friend Graham Alexander, who currently is performing as Paul on Broadway with “Rain.”

“It starts with the 1964 arrival of The Beatles in the U.S. The set design replicates the set of ‘The Ed Sullivan Show’ and we wear those costumes,” said Cates of the opening set that features “I Want to Hold Your Hand” and other early hits.

Next, the band goes into all-black outfits for what Cates calls somber music, including “If I Fell in Love With You.” The first half of the show ends on a much more colorful note.

“We do the full Sgt. Pepper suits and fancy lights,” said Cates.

Those suits and the show’s other costumes were researched and designed by Cates’ classmate Anna Grigo and constructed by her and a few others, including Whitney’s wife, Amy; the show’s costuming also includes a variety of wigs. Lighting design is by Brandon Koons who, like Cates, has worked for NMT in a professional capacity. Northport recording engineer Bruce Boege is handling sound, and the set design, stage management and poster art are the purview of Vanessa Bemis.

After intermission, “A Day in the Life” continues with The Beatles India-influenced period, then moves on to “Abbey Road” for the final set of songs.

“And yes, I am barefoot then,” said Cates.

“A Day in The Life: A Beatles Experience” is a major undertaking. Cates, who heads to the University of Maine in the fall, hopes its Camden Opera House production will mark the start of the work’s life on stage. The show has been a dream of his for years and he hopes that dream will come true in many places.

“We’ve gotten offers to perform it … I wrote it thinking about the future,” he said.

For now, though, pulling off such an ambitious production on such a tight budget is the reward, although Cates and company said they also hope to provoke dancing in the aisles and screaming girls in the front row.

“Plus, how great is it to learn all the Beatles songs,” Cates said.
