Task: Question Generation
Input (English): Passage: After the release of Highway 61 Revisited in August 1965, Dylan set about hiring a touring band. Guitarist Mike Bloomfield and keyboard player Al Kooper had backed Dylan on his new album and at Dylan's controversial electric debut at the 1965 Newport Folk Festival. Bloomfield chose not to tour with Dylan, preferring to remain with the Paul Butterfield Blues Band. After backing him at concerts in late August and early September, Kooper informed Dylan he did not wish to continue touring with him. Dylan's manager, Albert Grossman, was in the process of setting up a grueling concert schedule that would keep Dylan on the road for the next nine months, touring the U.S., Australia, and Europe. Dylan contacted a group who were performing as Levon and the Hawks, consisting of Levon Helm from Arkansas and four Canadian musicians: Robbie Robertson, Rick Danko, Richard Manuel and Garth Hudson. They had come together as a band in Canada, backing American rocker Ronnie Hawkins. Two people had strongly recommended the Hawks to Dylan: Mary Martin, the executive secretary of Grossman, and blues singer John Hammond, Jr., son of record producer John Hammond, who had signed Dylan to Columbia Records in 1961; the Hawks had backed the younger Hammond on his 1965 album So Many Roads.Dylan rehearsed with the Hawks in Toronto on September 15, where they were playing a hometown residency at Friar's Club, and on September 24, they made their debut in Austin, Texas. Two weeks later, encouraged by the success of their Texas performance, Dylan took the Hawks into Studio A of Columbia Records in New York City. Their immediate task was to record a hit single as the follow-up to "Positively 4th Street", but Dylan was already shaping his next album, the third one that year backed by rock musicians.
Output (English): What is the first name of the person who backed Dylan at concerts in late August and early September before leaving the band?
