the Hollywood Bowl tapes were given to him to see whether he could fashion an album from the material. Either Spector did not complete the job or his production was unsatisfactory, and the tapes sat unreleased for another six years. A complete tape of the August 1964 performance found its way out of the Capitol vault in the early 1970s and was the basis of a popular bootleg LP, Back in 64 at the Hollywood Bowl. The audio, while below professional release standards, was more than adequate for desperate hardcore fans and served for years as the standard recording of the summer 1964 tour. Finally, with a rival record label's impending release of the Live! at the Star-Club in Hamburg, Germany; 1962 album, consisting of a 15-year-old, poor-quality mono concert recording of the group performing in the Star-Club in Hamburg, Capitol Records' president, Bhaskar Menon, decided to revisit the Hollywood Bowl recordings. Beatles producer George Martin was handed the tapes and asked to compile a listenable "official" live album. When Martin heard the tapes, he was impressed by the performances but disappointed by the sound quality. In working on the three-track Hollywood Bowl concert tapes, Martin discovered quite a challenge. The first difficulty was finding a working three-track machine with which to play them. Once he found one, he discovered that the machine overheated when it was running, melting the magnetic tape. Martin and recording engineer Geoff Emerick came up with the solution of blowing air from a vacuum cleaner to keep the tape deck cool whilst the recordings were transferred to 16-track tape for filtering, equalisation, editing, and mixing. Although the original album sleeve says that the recordings were all made on 23 August 1964 and 30 August 1965, "Ticket to Ride" and "Help!" were recorded on 29 August 1965, and "Dizzy Miss Lizzy" is a composite using parts from both nights in 1965. A number of songs performed at the 23 August 1964 and 30 August 1965 concerts were not included on the album. Songs from the 23 August 1964 show that were not on the album are "Twist and Shout", "You Can't Do That", "Can't Buy Me Love", "If I Fell", "I Want to Hold Your Hand", and "A Hard Day's Night". Songs from the 30 August 1965 show that were not on the album are "I Feel Fine", "Everybody's Trying to Be My Baby", "Baby's in
