TIL the applause in Elton John's "Bennie and the Jets" was taken from a Jimi Hendrix performance and "fake-lived" by the audio engineers.

“He added reverb effects, applause and other audience sounds from John’s previous concerts and a loop from the Jimi Hendrix live album Isle of Wight, plus whistles, giving it the “live concert recording” feel”

Oh - ha I clicked. Damn

I'd heard they added clapping sounds on every beat of that track to imitate an audience that didn't know to clap on 2 and 4.
