Well, now we know why Mikkey Dee suddenly dropped out of touring with Thin Lizzy. Turns out the Motörhead drummer is simply going to be on the road with the Scorpions instead.

The band announced today that Mikkey Dee would be filling in on drums for James Kottak, who is taking a break to seek medical attention, during an upcoming U.S. run. Scorpions singer Klaus Meine had the following to say about Dee stepping in for Kottak:

“We would like to continue our Return to Forever tour with James, but we have to realize that his health is priority. We wish James a speedy recovery and he will be back to Rock with us very soon! We look forward to seeing all our fans this month.”

Dee is best known for his role in Motörhead. But prior to joining the group in 1992, Dee drummed in King Diamond and Don Dokken’s solo band. As for Kottak, the Scorpion drummer experienced some troubling times in 2014 that saw him step away from the band before returning last year. Whether the medical attention Kottak is currently receiving has any connection to his past troubles, though, remains unclear.

The Motörhead drummer will first take the stage with Scorpions at the Carolina Rebellion festival on May 6. The twelve U.S. date run will also include an appearance at Rocklahoma and a Las Vegas residency at The Joint At Hard Rock Hotel & Casino. More info on the upcoming dates can be found online.
