David Crosby and Graham Nash will perform at the 37th Annual T.J. Martell Foundation for Leukemia, Cancer and AIDS Research’s Honors Gala on October 23. The legendary songwriters, of Crosby, Stills, Nash and Young fame, will join a number of celebrities such as Randy Jackson, Grace Potter, Barry Gordy, Regis Philbin, Susan Lucci and country singers Little Big Town at the Gala. The event will take place at Ciprianis on 42nd Street in New York City. This year’s Gala has already raised more the $1.1 million for cancer and AIDS research and will likely raise much more. Tickets to the event can be purchased on the Foundation’s website.
