Five for singing

The musical athletes at tonight’s Vocal Olympics don’t have to worry about conditions on the slopes or in the rinks. The five competing groups from Massachusetts and Rhode Island just have to make sure they warm up their vocal cords, sing the right lyrics, and nail those harmonies. The finalists are Overboard, Alley Cats (pictured), 5-Alone, East Coast A Cappella, and Undertone. Tony Toledo hosts. 8 p.m. $10. Reservations are recommended.
