This weekend CMT will air highlights from Farm Aid 2000, held this past Sunday (Sept. 17) in Bristow, Va. The nearly nine-hour concert has been condensed into an hour-long special featuring performances by Farm Aid founder Willie Nelson and country artists Sawyer Brown, Travis Tritt and Alan Jackson. Nelson's fellow Farm Aid crusaders, rockers John Mellencamp and Neil Young, also are included. Mellencamp offers an acoustic version of "Dancin' in the Streets," and Young joins legendary group Crosby, Stills, Nash & Young for "Almost Cut My Hair." Tipper Gore, wife of vice president and presidential candidate Al Gore, joins Nelson on drums for the all-star finale. The special will air Saturday (Sept. 23) at 1 p.m. and 11 p.m. ET. The show will repeat Sunday (Sept. 24) at 10 p.m. ET. Billboard reports that attendance for this year's Farm Aid, which raises money to support America's family farmers, was 13,200, fewer than previous years according to concert organizers. Estimates originally put the crowd at around 25,000.
