Quick! If I asked you to name 20 or so of the region's finest singer-songwriters, the list would probably look something like this:

Josi Davis, Anne Castellano, Dogbite, Kevin Salley, Sherwood, Vincent Tuckwood, Coal Tattoo, Baird Welch-Collins, Golden Ratio, Micky Williston, Sandy Allen, Braiden Sunshine, Sue Menhart, Bruce McDermott, Dennis Walley, Clayton Allen,Tim Quinn, Daphne Lee Martin, Ben and Nancy Parent, and　Joe Glennon.

Remarkably enough, you can see all of these folks perform at one event when they gather Friday in support of the Fourth Annual "Pass the Guitar" benefit concert at All Souls Unity Hall in New London. As per the series' thematic construct, each artist plays one song on the same instrument.

Dogbite guitarist Hugh Birdsall organized the show and WCNI radio personality Dot Ames serves as emcee. The concert benefits the New London Homeless Hospitality Center. Soft drinks, coffee, tea and desserts donated by the Chocolate Rose Bakery are available for purchase and an auction will feature two sets of Sennheiser Momentum On-Ear Model Headphones as well as a ukulele donated by Spindrift Guitars.

Pass the Guitar, 7 p.m. Friday, All Souls Unity Hall, 19 Jay St., New London; $10 suggested donation benefitting Homeless Hospitality Center; hdbirdsall@aol.com.
