I watched a show about what the members of AC/DC do when they're not rocking - Brian Johnson likes to race cars. He tows his around behind his modest motorhome.

He was at a race when one of his competitors blew his engine up, and didn't have the scratch to rebuild it or buy another one, so he was going to drop out of the competition.

Miraculously, a crate showed up at the guy's trailer the next day with a new engine in it. Brian scored the guy an engine, and refused any thanks for doing it.

AC/DC not only plays great music, they are great people - 'cept Phil Rudd will have you killed if you piss him off.
