Peter, you can buy the musical notation matched up with lyrics from places like Sheet Music Direct and then, with some concentrated effort, match it up with the guitar tabs given on Guitar Tricks. I find it very helpful - the musical notation helps me figure out how to integrate the singing and the guitar strumming correctly. I find Songbird particularly difficult to sing with correct timing, probably because the words tend to land on the upbeat of the strum. I wonder if others find the vocal timing difficult?
