Not sure when this great article first appeared - lots of talk about The Band and backstage stuff regarding The Last Waltz - and this bit about Elvis Costello:

"Back in the spring of this year, at The Stone Pony club in Asbury Park, New Jersey, Jimmy Vivino organized a benefit show for Hubert Sumlin and put a few of us together to serve as his backup band. Hubert had been very ill and incurred huge medical bills. By God's good graces and a miraculous recovery, Hubert played that night like the master he is. I can't express what a thrill it was to play Wolf's stuff with his guitarist and bandleader showing us the way. The only "big star" to participate in the celebration was Elvis Costello. He sent a check for five grand towards Hubert's doctor's bills."
