THE BEAT GOES ON

Bob Dylan almost spat the words out in the studio of Chicago public television WTTW before a sleepy crowd of less than 200 at 2 a.m. on a Thursday morning. The song was a new one, fresh from the sessions for his new album. The band, which backed Dylan on the album, was also a new one: Rob Rothstein, bass; Howard Wyeth, drums; Donna Shea, fiddle.
