Song by the Beatles; editing, painting, and drawing, by me.
This is an edit of the from Anthology 1. The soft acoustic Karaoke version was made from the OOPS (out of phase sound). Go here to learn more about OOPS and Beatles recordings: http://www.beatletracks.com/btoops.html
Some of the lyrics may be a bit off. John's original recording is hard to make out sometimes, and I put in the words most of the internet agreed on.
The idea of looking at the sky as an ocean above you comes from Peter Gabriel's song "Downside Up" and a story he told about it on his Growing Up Live DVD.
BTW, I've been working on this on and off for 3 years...
PROTIP: "Free as a bird" sounds great backwards
