On December 8th 1975, Bob Dylan and his Rolling Thunder Revue rolled into New York City and the Madison Square Garden for the gig who was to be known as the "Night of the Hurricane". The Hurricane if course Rubin "Hurricane" Carter. The boxer who was wrongly convicted of murder. The show in Madison Square Garden was a huge fundraiser for Carter. He even spoke at the concert via telephone.
The Rolling Thunder Revue had quite a line-up, including: Bob Dylan, T-Bone J. Henry Burnett, Mick Ronson, Joan Baez, Allen Ginsberg, Roger McGuinn, Ramlin' Jack Elliott and Joni Mitchell. (Not everyone was at this concert, though).
The gig was the last stop of the tour and there was a farewell party in a uptown restaurant after. Dylan got the question right before the Rolling Thunder Revue started, why tour? The answer: "Why tour? 'Cause, uh, I think that's what I have to do. It's in my blood." And well, Dylan is still on tour.
