With curly tufts of a recognizable Jewfro peeking out from his omnipresent knit cap, Andy Frasco is a cross between John Belushi’s “Joliet” Jake Blues and Jimmy Buffett. He’s a band-fronting, songwriting party animal who turns into a swirling rock ‘n’ roll Tasmanian Devil onstage leading his U.N., not unlike Bruce Springsteen and the E-Street Band. From switching instruments mid-song to Frasco stage diving into the crowd or kibitzing with them, an Andy Frasco & The U.N. show is a celebration of inclusivity and tolerance where “You do You” and “let us do us.”
