Friday and Saturday nights, June 8 and 9, the waterfront Belfast Boathouse will rock, roll, laugh and maybe swoon a little with the beats, silliness and passions of the diverse popular music of the 1950’s. The nostalgic fun will begin both nights at 7:30 p.m.

Led by music director Rick Dostie at the keyboard and accompanied by veteran bassist Don Knowles from Marlborough and drummer Andy Clifford from Bangor, the 30-plus voice Belfast-based chorus will offer solos, ensemble and choral arrangements ranging from Broadway shows of the era to a medley arrangement of typical Top 40 tunes and hits from such as Bill Haley and the Comets and yes, Elvis.

The era’s doo-wop and scat — making rhythmic patterns with non-words — is a very old tradition … and looks very funny when written out in sheet music. The Penobscot Bay Singers, especially the younger members who had never heard the music, had a hard time singing it with a straight face for several rehearsals. They are working at making the music authentic and having a good time too, not hard to do with such gems as Warren Davis, George Malone and Charles Patrick’s “Book of Love” and Max Freedman and Jimmy DeKnight’s “Rock Around the Clock.”

Audience members will be encouraged to get up and use the space at the back of the hall to try out their old “Stroll” or “Chicken” moves or just twist away. Those for whom the 1950s were part of their youth may not be able to keep from singing along and that is just fine.

Admission price is $12, payable at the door. Refreshments will be served at the break. The Penobscot Bay Singers perform two other concerts each year in the Belfast area, at Christmas and near Easter. These feature classical and liturgical works both large and small. The group is ending its 39th season with the Pops and will start rehearsals again in September. New members (and returning) are always welcome as are donations, as member dues and concert income do not meet all expenses.

During the rest of the concert season, PBS is accompanied by Belfast resident Linnea Johnson and, when the budget allows, other instrumentalists from central Maine. Anyone interested in sponsoring a particular work or an instrumentalist or desiring more information about the group or to make a donation can write to Penobscot Bay Singers, P.O. Box 5, Belfast, ME 04915. The group is a 501(c)(3) organization.
