I believe it was and it was gonna be. If i remember correctly the album was almost ready to go but at the last second they remembered they did Sail On Sailor and decided to through that one on instead so they got rid of the weakest song on the album which was We Got Love.
They presented the album to Warner who rejected it because of the albums apprent lack of a hit single. So they cut We got love out and put Sail on, Sailor in it's place. The wrong tapes were sent out for pressing the album, so that's why on some very early versions of the album, Sail on, Sailor is missing and We got Love is there instead.
