Motley Crue is having a great summer with the top-grossing tour with Def Leppard but in a recent interview, Nikki Sixx remembers when things weren't going so well between band members and it hit a low point when Vince Neil's temper caused a show to be canceled in Rochester, NY. Before the show, backstage, the lead singer of Motley Crue was fixing himself a sandwich at the catered table when he noticed that the only mustard available was Grey Poupon. Vince was so pissed that he started screaming at the caterer that he had told them ahead of time no Grey Poupon! He then threw the jar against the wall and a piece of glass flew right back at him and lodged into his hand. No one could stop the bleeding so he had to be taken to the hospital and he never made it back in time for the show. Nikki called him a spoiled brat and the rest of the tour the band and crew gave Vince the cold shoulder for being, in Nikki's words, "a complete a**hole."
