OK, more 60's: After his motorcycle accident in '66 Bob Dylan spent a year of quiet introspection recovering both physically and spiritually. He altered his lifestyle and turned to The Bible. This 1967 classic from "John Wesley Harding" was inspired by Isaiah 21:5-9. He has performed it live more than any other of his songs. It was popularized by The Jimi Hendrix Experience in '68 - their only Top 40 hit in the U.S. at #20. Interestingly, ever since then Dylan has performed it a la Hendrix on stage. Dave Mason played 12-string acoustic on the recording and filled in on bass after Noel Redding left the sessions in anger. Hendrix himself played the bass line towards the end of the song. His version is ranked #48 on Rolling Stone's 500 Greatest Songs Of All Time. Featured in the "Forrest Gump" soundtrack.
Yesterday's answer: "Help!" by The Beatles. Great memories of my friends and I standing in line for HOURS at the Cinerama Theater (corner of Fernandez Juncos and Bolivar) in'65 in order to be the first kids in San Juan to watch "Help!".
