Nikki Sixx recently gave an interview to 95.5 KLOS, where he talked about his experience touring with Def Leppard. During the interview, he explained how the band supported them while they were dealing with Mick Mars’ departure from the band. Nikki praised Def Leppard for being supportive and helping them through a difficult time. He said (via Rock Celebries):
“It was so great. […] It was not of this competition we were literally putting on, and we went through stuff with obviously a band member leaving the band in the middle of the tour, and they were supportive of that. They know what it’s like to go through that hardship within a band. It was amazing, I can’t say enough great stuff about Mötley Crüe and Deff Leppard touring together.”
The World Tour, co-headlined by Def Leppard and Mötley Crüe, began in February 2023 and ended in November 2023. This tour was the first without the original guitarist, Mars, who was replaced by John 5. Mars announced his retirement in October 2022, leaving in the middle of two co-headlining tours: The Stadium Tour and The World Tour.
After his retirement, Mars sued the band, alleging that they were trying to remove him from the line-up of the band without his consent. The band later clarified that Mars was not fired but had retired on his own accord.
Def Leppard is now going on a 2024 tour, but this time without Mötley Crüe. Named ‘Summer Stadium Tour,’ the rockers will be co-headlining with Journey, along with Steve Miller Band, Heart and Cheap Trick. The Rock & Roll Hall of Fame bands had previously embarked on a tour together in 2018 and are set to perform at stadiums worldwide.
