Shakin' in the Sixties
Shakin' in the Sixties is a 1969 John Lennon improvisational composition he rattled off one day during the ill-fated Get Back sessions. It was never released and was never finished - if it was ever really started.
This song has not been included in any official compilation either, though a bootleg with Yoko Ono's voice on it is in circulation dubbed Shakin' in the Sixties / Yoko's Calling.
Students of the Beatles consider Shakin' in the Sixties to be an improvisation, a string of a couple of spontaneous jams that occurred in down moments during the recording session designed to bring the band back together in January of 1969. The song appears to have little or no musical structure with somewhat random, impromptu lyrics.
The longest fragment goes on for about 2 minutes.
