Wow! That is pretty neat. Those shows from 1968-1970 are pretty legendary. The 1969 show was the first show that Bob Dylan played after several years off the road because of a motorcycle accident. Jimi Hendrix played one of his last concerts ever at the 1970 Festival, and the Who performance from that year is out on CD and DVD and is absolutely incredible. I think the 1970 festival attracted 600,000 people and still holds the record for the largest show in the U.K.
