VIDEO: Jon Bon Jovi Shows Up at Billy Joel MSG Gig

Jon Bon Jovi was the latest special guest at Billy Joel's monthly residency show at New York's Madison Square Garden.

The Bon Jovi frontman joined "The Piano Man" on stage for two songs: "It's Still Rock and Roll to Me" and "Big Shot."

Joel's January 25th show at MSG was the kickoff to the seventh year of his residency at the iconic arena. The first show took place on January 27, 2014, and Joel has performed one show a month every month before a sellout crowd ever since.
