The downtown Camden Opera House will officially kick off summer with a tribute concert to the Allman Brothers and conclude Labor Day weekend with one of the finest folksingers of all time, Peter Yarrow of Peter, Paul and Mary.

In between the big holiday weekends, there will be an interactive large-scale musical family show from Montreal, “Forever Frozen”; the annual free community screening in partnership with Maine Public of “The Seal Who Came Home”; and a night of comedy with TV and film star and stand-up Caroline Rhea.

Summer night concerts include Las Cafeteras, a young group from Los Angeles playing a mishmash of punk, hip hop, beat, cumbia and rock on everything from a donkey jawbone to other traditional Mexican instruments; “Happy Days Are Here Again” from the Good Theatre in Portland, a Broadway-caliber singer performing the Barbra Streisand songbook; Maine native pianist and singer/songwriter Kate Schrock with Glen DaCosta (saxophonist for Bob Marley and The Wailers); and, returning for its fourth appearance at the opera house, the crowd-pleasing “A Day in the Life: A Beatles Experience,” the Camden native Morgan Cates-produced multimedia tribute. The popular CIFF Selects documentaries will screen July 19 and Aug. 16.

Also, beginning June 30 and continuing through Sept. 15, historic tours of the Opera House are offered at Fridays at 4:45 p.m. The tour includes a four-minute slideshow on opera house history, followed by a tour of the main theater and behind the scenes peeks. The full downtown tours begin 4 p.m. at Camden Public Library; call 236-3440 for more information.
