Well, his voice is as rough as sandpaper, but the man knows his lyrics and has impeccable comic timing. For the past two Mondays, at Joe's Pub in Manhattan, bearded, burly composer William Finn (Falsettos) has sung a few of his own tunes with elan, volume and unbridled enthusiasm. To hear what that sounds like yourself, you better hurry, as Oct. 9 is the final night of the cabaret act, titled "Infinite Joy: Songs of William Finn (or Mostly Unknown Songs Written Recently and Not So Recently)." Joining Finn for the program have been such performers as Carolee Carmello, Stephen DeRosa, Wanda Houston, Lewis Cleale, Mary Testa and Norm Lewis. The show, as the title suggests, features some rarely performed Finn tunes; tunes from Falsettos, A New Brain and other Finn works; as well as a selection from the upcoming The Royal Family of Broadway. Tickets range in price. For more information, call (212) 239-6200.
