Liza Minnelli is set to perform with her half-sister Lorna Luft for the first time in 20 years at two upcoming cancer charity fundraisers. Judy Garland's daughters have not appeared onstage together since they duetted at the 1993 Tony Awards, but the singers will reunite for fans at two New York gigs next month (Oct13) to raise money for the fight against breast cancer. The Nothing Like a Dame: Lorna's Pink Party events will take place at the Birdland jazz club on 14 and 21 October (13), and will also feature singers Phyllis Newman and Ann Hampton Callaway, theatre stars Nick Adams and Jim Caruso, and actress Marcia Strassman. The cause is particularly close to Luft's heart because she was diagnosed with breast cancer earlier this year (13). Luft says, "This event means the world to me. I'm so grateful to be feeling so well and performing again. These two Birdland nights are the perfect opportunity for me to gather some friends - including my sister - to raise money to help two essential organisations." Proceeds will benefit the Phyllis Newman Women's Health Initiative and the Dr. Philomena McAndrew Fund of Tower Cancer Research Foundation.
