Tip of My Tongue
Tip of My Tongue has little to do with the Beatles. It was written by Paul McCartney, and while credited to both Lennon and McCartney, John denied any role in writing it, referring to it later as "Paul's rubbish."
The Beatles never released it, and the only effort to record it (on November 26, 1962) has not survived, either officially or in bootlegs.
The person who did record Tip of My Tongue was a young singer named Tommy Quigley, who came under the management of Brian Epstein. Epstein changed his name to "Tommy Quickly" for stage purposes. He was heavily promoted in 1963, and he even opened for the Beatles on three tours. He also opened for Billy J. Kramer and for Gerry and the Pacemakers.
His debut single was this "Lennon/McCartney" song, but It was a failure. In fact, it is the only song credited to the Lennon/McCartney that failed to chart in the UK upon its release.
Quickly went on to produce four more singles before throwing in the towel. He never became a success, in spite of the exposure with the Beatles and other acts and management by veteran Epstein. His label (Pye) eventually dropped him in June of 1964. The Remo Four, an obscure back-up group, also appears on the record.
