Al Kooper on Bob Dylan's record producers Tom Wilson and Bob Johnston

"In 1966 Dylan went down to Nashville for Blonde On Blonde He stayed out in the studio 10 or 12 hours. Bob never left it. He'd eat candy bars and drink milk shakes. I told the musicians to 'go away and to do anything you want to and be in phone contact. Don't go home... you can be in the studio down here if you need some beds or something'."
