Def Leppard pissed off hockey fans over the weekend during a live performance at the NHL’s opening night ceremonies at the Fox Theater in Detroit. No, it wasn’t because the British rockers refused to play “Love Bites.” As you can see in the video footage below, after Red Wings forward Darren McCarty drove out on to the stage on a motorcycle to triumphantly hand the group’s frontman Joe Elliott the coveted Stanley Cup, the singer proceeded to walk over and display it … upside-down! You know it’s bad when even The Tehran Times is calling out your blunder. Elliott shrugged off the whole faux pas by saying, “We’re soccer boys, what do we know?” Maybe next year they can get Nickelback? ―Aidin Vaziri
