 Lennon described the noise as "wild" and also twice as deafening when the Beatles performed.On-stage "fold-back" speakers were not in common use in 1965, rendering the Beatles' playing inaudible to each other, forcing them to just play through a list of songs nervously, not knowing what kind of sound was being produced, or whether they were playing in unison.The Beatles section of the concert was extremely short by modern standards (just 30 minutes) but was the typical 1965 Beatles tour set list, with Starr opting to sing "Act Naturally" instead of "I Wanna Be Your Man".
