Billy Joel’s sold out gig at Madison Square Garden Friday night was moving right along when about half-way through the show the Piano Man turned to his sea of giddy fans and introduced AC/DC’s Brian Johnson—a surprising twist that electrified MSG and brought hundreds to their feet.

Johnson shot-putted onto the stage as cheering fans—many of whom were caught entirely off guard by the show’s abrupt pivot—and grabbed the mic to perform his band’s hit “Shook Me All Night Long.”

Soon, the whole crowd was singing along, and Joel, who had no problem taking a backseat during his own show, rocked along by his piano.

Johnson, whose one-song performance sent the Garden crowd into a frenzy, capped the performance by wrapping his arms around Joel before exiting the stage.
