Another live album that needs to be mentioned is George Harrison's and Ravi Shankar Concert for Bangladesh on August 1, 1971.
Organized for the relief of refugees in East Pakistan (now independent Bangladesh). Eric Clapton was in the grips of a heroin addiction he couldn't practice for the event, had to play a different guitar that was not his, but according to Harrison Clapton "was brilliant" Bob Dylan played live for the first time in awhile, and John Lennon was even going to show yo but left NY after an argument with Yoko.
This concert had an outstanding line up and is well worth a listen
