Roots of Mike Barson

"I'm Only Sleeping" is a song by the English rock band the Beatles from their 1966 studio album Revolver. In the United States and Canada, it was one of the three tracks that Capitol Records cut from the album and instead included on Yesterday and Today, released two months before Revolver. Credited as a Lennon–McCartney song, it was written primarily by John Lennon. The track includes a backwards lead guitar part played by George Harrison, the first time such a technique was used on a pop recording.
