The audio track is from the CD commemorating the concert and while I had to make some adjustments in speed to match the video, it sounds a hell of a lot better. CCR was a hit making machine and sold more records than the Beatles in 1969. John Fogerty was a special talent, a marvelous singer and terrific guitar player. Doug Clifford, Stu Cook and Tom Fogerty were good musicians and deserved better than what happened to end this remarkable American band.
