Cover art for Come And Get It lyrics by Paul McCartney

yes, Paul did a great demo of this song (which is included on Anthology 3). I always liked the irony that a big named star like Paul McCartney 'gave' a hit song to a group and the song had lines like "If you want it, here it is come and get it", and "will you walk away from a fool and his money". Seems like an autobiographical song about itself.
