Who calls him Macca?

Some gal named Rayna.

“I’m from Liverpool and they abbreviate everything in Liverpool,” McCartney explains. “McCartney is a bit too formal for ‘Hey, Macca.’ So, George Harrison, ‘Hey, Hassa.’ John Lennon, ‘Lenny.’ So, they just abbreviate everything there and so that’s why. It’s a derivation of McCartney.”

Another relief! It’s not a derivation from the dance name. I never did see him do it.
