John Bucchino — the acclaimed singer-songwriter whose works have been recorded by Patti LuPone and Barbara Cook — has extended his run at the Duplex and will play Wednesday evenings at 9 PM throughout the month of August. Bucchino has written songs for the musicals The Artist at 40, Urban Myths and Lavender Girl as well as the animated film "Joseph, King of Dreams." His CDs include "Grateful, The Songs of John Bucchino" and "Solitude Lessons." Saturdays in August will feature the sounds of cabaret veteran Baby Jane Dexter, who is currently entering her sixth smash month at the Duplex. Dexter will offer performances at 9 PM. Another cabaret regular, Barbara Fasano, will perform 7 PM shows on Saturdays, Aug. 16 and 23. Fasano's shows include tunes by Julie Gold, Bruce Springsteen and Ervin Drake.

Sundays at the Duplex will boast cabaret's Natalie Douglas and Broadway's B. J. Crosby. Douglas, who has been compared to the late Nina Simone and Billie Holiday, will play Sunday evenings at 7 PM. Crosby, most recently on Broadway as Matron "Mama" Morton in Chicago, will belt out tunes Sundays at 9 PM. Crosby also starred on Broadway in the recent revival of One Mo' Time, and she earned a Tony nomination for her work in Smokey Joe's Cafe.
