Willie Nelson and jazz vocalist Dianne Reeves will perform at the T.J. Martell Foundation's 34th annual fundraising gala taking place Oct. 28 at the Hilton New York Hotel in New York City. The foundation is devoted to research to find cures and treatments for leukemia, cancer and AIDS. The gala will also honor the late Michael Jackson with the organization's Legend Award. Jackson is the single largest donor in the T.J. Martell Foundation's 34-year history. Nelson performed Sunday (Oct. 4) at Farm Aid 2009 near St. Louis during an all-day show that also featured Jamey Johnson, Gretchen Wilson, Ryan Bingham & the Dead Horses, Wilco and Jason Mraz, along with Nelson's fellow Farm Aid board members Neil Young, Dave Matthews and John Mellencamp.
