In May 1965, Dylan returned from his tour of England feeling exhausted and dissatisfied with his material. He told journalist Nat Hentoff: "I was going to quit singing. I was very drained." The singer added, "It's very tiring having other people tell you how much they dig you if you yourself don't dig you."  As a consequence of his dissatisfaction, Dylan wrote 20 pages of verse he later described as a "long piece of vomit". He reduced this to a song with four verses and a chorus--"Like a Rolling Stone". He told Hentoff that writing and recording the song washed away his dissatisfaction, and restored his enthusiasm for creating music. Describing the experience to Robert Hilburn in 2004, nearly 40 years later, Dylan said: "It's like a ghost is writing a song like that ... You don't know what it means except the ghost picked me to write the song."  Highway 61 Revisited was recorded in two blocks of recording sessions that took place in Studio A of Columbia Records, located in Midtown Manhattan. The first block, June 15 and June 16, was produced by Tom Wilson and resulted in the single "Like a Rolling Stone". On July 25, Dylan performed his controversial electric set at the Newport Folk Festival, where some of the crowd booed his performance. Four days after Newport, Dylan returned to the recording studio. From July 29 to August 4, he and his band completed recording Highway 61 Revisited, but under the supervision of a new producer, Bob Johnston.
