One of the founding members of Def Leppard--bassist Rick Savage--turns 51 today, born December 2, 1960 in Sheffield, South Yorkshire, England.

Rick and Joe Elliot are the only remaining original members of the band.  Both Sav and Joe, as well as Rick Allen, are the only bandmates to have performed on every Def Leppard album.
