In the summer of ‘62, Dylan is talking to his friend Glover’s tape recorder. The singer’s girlfriend, Suze Rotolo, is on a prolonged trip to Italy and he’s “feeling more than kind of blue,” Wilentz said. “And he talks about it to the tape. ‘I’ve written a song. Well, only the last verse. And now we’re going to sing it.’ He says, ‘It’s not in my style. This is Pete Seeger style. Do you know who Pete Seeger is? He’s Mike Seeger’s older brother.’ Then he starts singing the song and it’s an early version of ‘Tomorrow Is a Long Time.’ That’s an amazing moment. You could hear how his artistry began to take shape.”

“Eternal Circle,” “Liverpool Gal,” “West Memphis”

“This one was kept under lock and key,” Wilentz said. “It’s amazing for all kinds of reasons. The one that’s going to get the most attention is ‘Liverpool Gal,’ which is a song Dylan wrote about his time in London. That winter of ‘62-‘63. No one’s heard it. It’s been talked about. It’s not a No. 1 Dylan but it’s a very good song.”

Dylan also sings a new song called “Eternal Circle.”

“He points out what that song is all about. The banter is very interesting, though not as interesting as the song. At one point, he and Glover start jamming. They do a song called ‘West Memphis.’ They were making it up as they go along. To hear Bob Dylan and Tony Glover do a duet, that was precious. It’s a couple of guys sitting around having fun. It’s not a performance for the ages. But it’s two very talented old friends playing this new music in new ways.”
