Mick Mars opened up about his music plans as his health diagnosis continuously affected his life even more.

The Motley Crue co-founder, who has since been replaced by John 5 in the band, announced his retirement from touring following the band's final tour stop at the Allegiant Stadium in Las Vegas, Nev. He performed the final song of that night, "Kickstart My Heart," before embracing his bandmates onstage.

Mick Mars Shares Health Update

After the final tour, his representative released an exclusive statement to Variety and confirmed his retirement from touring due to ankylosing spondylitis. He has since been replaced unexpectedly with John 5, leading him to file a lawsuit against the band.

Amid his health struggles, Mars sat in a new interview with Jonathan Clarke on the "Out of the Box" podcast saying that his health issue has affected his body and his future musical endeavors.

"Oh, yeah. I'm fine, you know? My A.S. is what it is. There's nothing I can do about that," he said of his arthritic disease. "From the rigors [and] the hard stuff, like flying here and doing this. That crap is a little difficult for me to do nowadays because I'm almost a solid bone now. It got a little rough, but that doesn't mean I'm not gonna do a lot of music."

His statement led Clarke to ask him whether he would hold a limited live performance, to which Mars said he could do a one-off or a residency for a couple of nights. However, he clarified that he could no longer have flights or travel because of his age and health.

No One Expected Mick Mars' Touring Retirement

Speaking with Guitar World Magazine, Nikki Sixx opened up about his former bandmate and how it was never expected that he would not be able to tour with them again.

"[With John] knowing all the members of the band, and me having this relationship with him writing and as friends, and even being in the studio with him writing stuff with the band for [the soundtrack to] 'The Dirt,' it felt like a no-brainer in a horrible situation something we did not ask for or want," he said.

Mars opened up about his diagnosis in the band's 2001 biography, "The Dirt," saying that he started struggling with the disease when he was a teen.
