Toby Keith displays his 82nd Airborne Division jersey while autographing red cups for service members following his concert on Bagram Air Field April 29. "Red Solo Cup" was never released as a single, but became a YouTube sensation. Hundreds of service members in the crowd turned out with red cups in hand to wave in the air as Keith performed the song. "You have no idea how many thousands of red cups I've put my name on over here," said Keith.
