People don't know every song any performer sings when they see them live? I never understood that logic, I don't want to know each and every song a performer is going to do.
That's a problem with McCartney's Beatle heavy setlist now, it's too predictable, he needs to change it up big time!
As for Girls school, it's absolutely fantastic, the hardest rocking song by Wings without a doubt and McCartney should be performing it! In fact he has so many wings rockers that are just screaming to be performed live! It's really a shame that he doesn't play these great songs!
