Watch Bon Jovi make a suprise appearance on stage with Billy Joel!

Billy Joel fans got a surprise on Saturday At Madison Square Garden

By Jon Smith:

Jon Bon Jovi dropped in for an unannounced guest appearance with Billy Joel in NYC this past weekend, which of course fans were stoked about. Fans cheered as Bon Jovi joined in for “It’s Still Rock and Roll to Me” and “Big Shot” at Madison Square Garden.

I just realized that Billy Joel has played MSG once a month for the past seven years.  SEVEN YEARS, man.  That’s awesome
