"Paperback writer" was one of the group's finest 45's. The B-side of "Rain" was a sign of things to come.
The two songs were introduced on The Ed Sullivan Show in 2 fantastic promo films. They were available on YouTube but no more.
The Beatles released 3 LPs between Christmas 1965 and the summer of 1966. However, "Paperback writer", or the B-side of "Rain", were not included in the US versions of "Rubber Soul", "Yesterday and today" or "Revolver".
Why wasn't this 45 included in the "Revolver" LP? It seems to fit that one beautifully.
P.S. You can listen to my show (Canto Talk) and follow me on Twitter. By the way, the book below has "a song by song" story of every one recorded and released by the group. It is a wonderful resource to remember all of those tunes that we listened to on vinyl many years ago.
