Music, lots of food, whoopie pies, games and other activities will mark the official launch of the long-awaited Thomaston Green project at a festive celebration Saturday, July 24 from 11 a.m. to 2 p.m. on the former prison site.

The Thomaston Green Public Celebration will feature a ribbon-cutting ceremony and the opening of a trail along the St. George River, part of the planned project that envisions a central green connecting Main Street to an overlook along the river, a branch of the YMCA, neighborhood businesses and 30 low-maintenance homes.

“It’s a great opportunity to celebrate who we are as a town and where we are headed together,” said Thomaston Town Manager Valmore Blastow, in a news release. “We’d like to extend a welcome to those from out of town, who want to see how great a community we are.”

Three distinct types of music will offer something for every musical taste from rock ‘n’ roll to the distinctive island sound of a steel drum band. Local restaurants will offer delectable specialties from their menus; volunteers will cook hamburgers, hot dogs and fries; and some local businesses will offer information about their products and services.

A group planning to launch a full-scale farmers market in Thomaston this summer will start with a mini-farmers market at this event.

Contributing music to the festivities are Steelin’ Thunder, a nonprofit community steel drum band with 17 members from eight Midcoast towns who deliver the infectious Caribbean sound of the big metal drums. Proceeds from their performances go to scholarships for Midcoast high school graduates studying music in college.

Dory in the Desert, a local rock/folk/jazz band that’s been entertaining in the area for five years, will play both cover tunes and the original music of singer/songwriter Angela Anderson-Pomerlau, with Mike Garrigan on drums, Dan Murdock on bass and Mike Whitehead on trumpet.

The Mid-Coast Community Band has played together since its founding in 1986 and includes local musicians of all ages. The all-volunteer band performs often at local festivals and parades, and holds regular spring, fall and Christmas concerts. Often the band raises money and offers scholarships for young musicians.

Food will be provided by local restaurants, including the Thomaston CafĂ©, Waterfront Market, F&A’s Market, Applebee’s, Athens Mediterranean Pizza, Harborview and Pik Quik. Participating businesses include Mystic Woodworking and Lyman Morse.

Bakers from the Thomaston Friends of the Library will offer a variety of whoopie pies. Local author Nancy Griffin will be on hand in the library booth to sign copies of her book “Making Whoopies: The Official Whoopie Pie Book.”

Organizations that will take part in the event include the Thomaston Historical Society, Montpelier, the Thomaston Public Library, local churches, the planned farmers market, the Georges River Land Trust, and the Conservation Commission. Games for children will be organized by Julie Russo.
