I've just got The Beatles Little Black Songbook which has lyrics and chords to over 160 Beatles songs loaded on my iPhone.
It also has a few instructional video lessons to help you learn songs, one of which is And Your Bird Can Sing which I've always wanted to play, (the lead bit that George did, or was it Paul?). I can half play it now!
According to the app its all official etc.
