Backing track by Karaoke Diamonds and purchased on iTunes. Original song written and recorded by Paul Simon.

After Birch left Grizzly, Stoat, and Young, while he was trying to record a solo album, he took some time off to do an abortive tour of coffee shops. When the money earned was barely enough to get him to the next gig, he stopped.

Imagine him waiting for a train to take him to his next gig, sitting on his suitcase, getting out his guitar, and singing this.
