NYT interview w/D A Pennebaker, who made the (wonderful) documentary "Don't Look Back" about Dylan's tour of England.

How did you film the famous opening sequence for “Subterranean Homesick Blues”?

We first tried to do it in the garden of the hotel, and a cop came along and was grabbing me and telling me to stop. So we went into the alley, where there were no cops, and we did it just one time, and we just stuck a tape recorder in front of Dylan and it played the song. We had done the signs the night before, and Donovan had helped — Donovan was a very good artist, it turns out — and Joan Baez. I think I’d even done some, but I can’t remember which ones. [laughs]
