Willie Nelson walks off stage minutes before show in Charlotte Saturday

Willie Nelson canceled his concert at PNC Music Pavilion Saturday minutes before the show was scheduled to start.

Live Nation, the concerts promoter, said in a tweet, "due to illness, Willie Nelson is unable to play tonight at the Outlaw Music Festival at PNC Music Pavilion. Fans are asked to hold on to their tickets until a new date is announced."

TMZ reported that the 85-year-old country music legend had a stomach bug Saturday night as he was about to go on stage at PNC Music Pavilion. A representative told TMZ that Nelson is feeling better and is still set to play Sunday night in Washington, D.C.
