The Song:"I've Just Seen A Face" is a Beatles song, from their album,
Help!. It was written by Paul McCartney.
Paul McCartney, in 2015, was performing at a PETA party/benefit show. Beck joined him on stage to sing two Beatles songs (this one and "Drive My Car").
Also fascinatingly, way back in the early 90s, there is a demo tape on which Beck and Steve Hanft re-wrote this song as "I've Just Seen A Face Lift."
