Phil Collen appears to be in violation of the two necklace minimum.

Damn—Vivian Campbell has been in Def Leppard for 20 years. While they’ve never scaled Hysteria-like heights during that period (both ’99’s Euphoria and ’02’s X peaked at #11 on the Billboard 200) the band has remained a popular attraction.

Shockingly both Campbell and Phil Collen are shirtless in the inset pics.
