During and between tours, Dylan and the Hawks attempted several recording sessions, but with less than satisfying results. Sessions in October and November yielded just one usable single ("Can You Please Crawl Out Your Window?"), and two days of recording in January 1966 for what was intended to be Dylan's next album, "Blonde on Blonde", resulted in "One of Us Must Know (Sooner or Later)", which was released as a single a few weeks later and was subsequently selected for the album. On "One of Us Must Know", Dylan was backed by drummer Bobby Gregg, bassist Danko (or Bill Lee), guitarist Robbie Robertson, pianist Paul Griffin, and Al Kooper (who was more a guitarist than an organist) playing organ. Frustrated by the slow progress in the New York studio, Dylan accepted the suggestion of producer Bob Johnston and moved the recording sessions to Nashville. In Nashville, Robertson's guitar was prominent on the "Blonde on Blonde" recordings, especially "Leopard-Skin Pill-Box Hat", but the other members of the Hawks did not attend the sessions.
