This celebration of sexuality directed by Daryl Nitz has been remounted after a run last summer with one new cast member and some song changes–and it’s only gotten better. The three original singers and pianist Claire Bigley have been joined by fluid-voiced Ty Perry, who adds sexy panache to what was already a naughty romp. The lyrics are indeed explicit: these tunes–which range from 1920s music hall numbers to Depeche Mode’s “Somebody”–cover almost everything from masturbation to group sex to outrageous fantasies to S and M. But the ensemble also sings about longing and loss and the strenuous uphill road to true love. Each number is introduced by an embarrassing or poignant story from the performers’ own lives–and this time there’s more warm, casual banter between them. Group diva Gillian Kelly, who has an operatic voice, wears a tiara as she flutters through a number worrying that her new lover might be gay. Gail Becker sings wryly about seducing a utility-company worker, and Kristofer Simmons soulfully recounts the difficulties of being bisexual. Perry’s knockout voice adds flash to “I Don’t Know How to Love Him,” which becomes unbelievably funny with the aid of a few well-placed props. Davenport’s Piano Bar & Cabaret, 1383 N. Milwaukee, 773-278-1830. Through April 24: Saturdays, 10:30 PM. $20 plus two-drink minimum.
