I was happy to find this footage of Bob Dylan at the Concert for Bangladesh singing "Love Minus Zero/No Limit." Then he is joined by George Harrison with "If not for You." Great quality video, and great fun looking back to those days.
Continuing with Dylan covers on Bob's Birthday today, Eric Clapton gives a soulful rendition (with some ethereal guitar solos) of Love Minus Zero/No Limit and Don't Think Twice, It's Alright.
