Last month, Mr. Big's regular drummer Pat Torpey revealed he is battling Parkinson's disease. Pat also announced he would be cutting back on band duties, although he is expected to join the band on some tracks and participate in the group's acoustic set.

Matt will step in at Mr Big's upcoming dates, which includes one UK gig at London's Koko on October 17.

Matt Starr, who will remain the drummer for Ace Frehley, says in a statement:

"I'm grateful to announce I will be filling in for Mr Big drummer Pat Torpey on their upcoming tour. Pat is an exceptional drummer and an inspiration for many reasons."

Mr Big's eight album, 'The Stories We Could Tell', will launch on September 30 via Frontiers Records. Despite his condition, Pat did complete all of the drumming on the album.
