Billy Joel brought out a very special guest for his latest residency show at New York's Madison Square Garden Friday. AC/DC singer Brian Johnson to do "You Shook Me All Night Long" with Billy and his band.

Billy’s guitar tech, who goes by the name Chainsaw, has been doing his version of AC/DC’s "Highway To Hell" during Billy's show for years, so this was familiar territory for the band.

Here’s some fan-shot video of Brian’s performance with Billy!!!
