Thanks to M.Ted for acharacteristically complete answer. Don't apologize, Ted ~ even if your input is not for everybody, there's always a few of us (certainly including the original questioner) who want the help we can get.

One-chord songs (or songs like this one, where the entire verse, if not the chorus, is on one chord) are pretty dern difficult to perform well. Especially for beginnners, and especially for anyone trying to learn the song from paper.
