Billy Joel and Def Leppard Jam at Fenway

Billy Joel  had a special guest this weekend in Boston: Joe Elliott from Def Leppard!

Joe jumped on stage last Friday night at Fenway Park for a rendition of “Pour Some Sugar on Me,” from the album, Hysteria.

Billy loves having special guests in the mix at his shows. Bruce Springsteen recently joined The Piano Man at Madison Square Garden.

Joel plays the Garden on Aug. 23. Who should he bring on stage next?
