Just watched a film called Magic Trip. It's a documentary about writer Ken Kesey (One Flew Over the Cuckoo’s Nest) and the band of Merry Pranksters, who were pioneers of the hippie era. Most of it consists of live footage shot in 1964, taken during a drug-fueled trip in an old school bus, painted in psychedelic colors, when Kesey and the Merry Pranksters rode across the country from the West Coast to New York to visit the 1964 World's Fair, Timothy Leary, and various people associated with the Beat movement. The bus driver of this stoned group of wanderers, for the first half of the trip, was Beat figurehead Neal Cassady, who appears in the film. There is also some early footage of Grateful Dead, as Jerry and his band mates were working closely with Ken Kesey during the Acid Test period. An excellent piece of 1960's history, very enjoyable to watch.
Just wanted to add that, although the footage is old, the film is recent - it was made by Oscar-winning director Alex Gibney. The DVD came out in 2011, and I borrowed a copy from the local library. The Boston Globe said, "It's the movie Yellow Submarine should have been but didn't know how to be".
Just look for anything about Ken Kesey, Abbie Hoffman, Jerry Rubin, Timothy Leary etc. And READ IT!!!
