If you happened to see Billy Joel on Jimmy Fallon this Friday, you'll know that the Piano Man is currently in the middle of a residency at New York's Madison Square Garden. The legendary singer's no stranger to a cover song or two and even strays from his usual pop into hard rock territory.
Whilst playing at MSG, Joel invited AC/DC's Brian Johnson onstage to sing the 1980 hit 'You Shook Me All Night Long'. It's a bit messy in places, but you can see they're having a ball.
We'd have preferred something more recent, like say 'War Machine', but you can't have everything.
