Cheap Trick drummer Bun E. Carlos was recently surprised to be left off a new recording by the band, which also appears to be recorded without his permission. Carlos told billboard.com in an email exchanege, “I’m a full member of Cheap Trick in all respects. Solely as an accommodation to some of the band members, I reluctantly agreed to take a temporary hiatus from touring. The other members have never seriously talked to me about my leaving the band permanently.” The song is included in a Christmas album that benefits the Special Olympics.

Carlos (born Bradd Carlson) is an original member of Cheap Trick, having formed the band in 1973 with vocalist Robin Zander, bassist Tom Petersson and guitarist Rick Nielsen. He hasn’t toured with the band for about two years, with Daxx Nielsen (Rick’s son) filling in. “I’m a full member of Cheap Trick in all respects,” he said. “Solely as an accommodation to some of the band members, I reluctantly agreed to take a temporary hiatus from touring. The other members have never seriously talked to me about my leaving the band permanently.” During his hiatis, Carlos has founded and played with a band called Candy Golde and he’s also a member of Tinted Windows.

The song will be on “A Very Special Christmas – 25 Years,” which benefits the Special Olympics. Calos added, “The Special Olympics was as surprised by this as I was…they had no idea I wasn’t on the record. And, I don’t want them to lose an opportunity to support this great cause because of this. But Tom, Rick, and Robin simply can’t make a recording without me and call it Cheap Trick.”

A rep confirmed it’s “possible” that Carlos may take legal action, but Carlos asserts he’s “looking after my interests in Cheap Trick and doing my best to make sure we stand for what is great about rock ‘n’ roll.”

Here’s the statement Carlos posted on his website:

Bun E Carlos, Cheap Trick’s founding member and longtime drummer joins all Cheap Trick fans in supporting the Special Olympics, but wants all his fans to know that he was not invited to participate in the track attributed to Cheap Trick scheduled to be on the Special Olympics Christmas album. Bun E stated, “There are no Led Zeppelin records without John Bonham and there’s no Leave It To Beaver without Jerry Mathers! I remain humbled and grateful for the support of Cheap Trick’s fans and please support www.specialolympics.org and their very important initiatives.”
