The master take of "Positively 4th Street" was recorded on July 29, 1965, during the mid-June to early August recording sessions that produced all of the material that appeared on Dylan's 1965 album, Highway 61 Revisited. The song was the last to be attempted that day, with Dylan and a variety of session musicians having successfully recorded master takes of "It Takes a Lot to Laugh, It Takes a Train to Cry" and "Tombstone Blues" earlier. The studio band on "Positively 4th Street" featured Robert Gregg (drums), Russ Savakus (bass), Frank Owens (piano), Al Kooper (organ) and Mike Bloomfield (guitar), with the song initially being logged on the studio's official recording session documentation under the working title of "Black Dalli Rue".
This is a cool video.
Also, there WAS a really cool image generator where you could script the cue cards in Bob Dylan's iconic "Subterranean Homesick Blues" video. It was on the Sony/BMG UK website. Sadly it's now disappeaered so I've edited and removed the link.
