A famous heavy metal singer is explaining why he abrupt retired, forcing his band to cancel 50th anniversary tour plans.

Dee Snider said on his “House of Hair” radio show that he resigned from Twisted Sister due to health issues. However, he wants to assure fans that he’s not dying.

“The rumors have run wild that I am on my death bed,” Snider said. “I am not. I just can’t do those things that I did in my 20s, 30s, 40s, 50s and even 60s. Alright? Otherwise I’m alive and well. I’m enjoying life.”

Twisted Sister was scheduled to begin its first tour in 10 years this April, but Snider said he couldn’t perform at the same levels he used to. All concerts were canceled.

“You won’t see me on the stage kicking ass like I used to because that will mess me up,” Snider explained. “Thank you very much for cheering me on. I’m OK. I just can’t do that anymore. And you know what? The truth of the matter is: I don’t want you to see me up there being less than you expect me to be. You got memories of a great show that I did? That’s what I want to leave you with.”

According to Ultimate Classic Rock, Snider also detailed issues with degenerative arthritis in his shoulders, high blood pressure and a recent hip replacement surgery during a conversation with his son Cody Blue on “Acid for Squares.“ Snider, 70, said he’s been sober his entire life but started taking mushrooms in an effort to lower stress levels on top of medicine from doctors to bring his blood pressure down.

“I always told myself because I [saw] the tremendous effects medicine plants have had on my family, physical changes it’s made in them — I always said if I needed to, if it would help me in a situation sometime in the future, I would try it. I would welcome it,” Snider said. “It was very psychedelic, for lack of a better word, very organic, moving.”

Twisted Sister guitarist Jay Jay French said last week that the band is considering continuing on without Snider. Potential replacements for the frontman have not been announced.

Snider, French, guitarist Eddie Ojeda, drummer Joe Franco and bassist Russell Pzutto were all expected to be part of the Twisted Sister tour. Classic-era bass player Mark Mendoza, who performed on hits like “We’re Not Gonna Take It” and “I Wanna Rock,” would not be part of the reunion tour due to “irreconcilable differences,” Snider previously said. A.J. Pero, who played drums on all of Twisted Sister’s albums, died in 2015.

Twisted Sister was one of the biggest bands of the hair metal/glam metal era, forming in the 1970s and releasing five albums in the ‘80s. Popular songs include “We’re Not Gonna Take It,” “I Wanna Rock,” “Hot Love,” “The Kids are Back,” “You Can’t Stop Rock and Roll,” and a cover of the Shangri-Las’ “Leader of the Pack.”

Twisted Sister last performed on Nov. 12, 2016, on their “40 and F— It” farewell tour. For years, Snider insisted he had no interest in reuniting, though he did join Mendoza and French for a 2023 performance when Twisted Sister was inducted into the Heavy Metal Hall of Fame.

Snider is also known for his film and TV work, including appearances on “Cobra Kai,” “The Celebrity Apprentice,” “Holliston,” “The Last Sharknado: It’s About Time,” “Metal: A Headbanger’s Journey,” “Pee-wee’s Big Adventure,” “The Masked Singer,” and “SpongeBob SquarePants.”
