 "I'm Only Sleeping", "And Your Bird Can Sing" and "Doctor Robert" were the tracks omitted from Capitol's version of "Revolver".In the case of "I'm Only Sleeping", the version issued on "Yesterday and Today" was a different mix from that included on EMI's "Revolver".Due to the exclusion of the three Lennon tracks, there were only two songs on the Capitol release for which he was the principal writer, compared with three by Harrison and six by McCartney.
