The singer and bassist, who briefly fronted Black Sabbath in the 1980s, had previously announced plans to kick off the trek in his native U.K. from 8 November (16), with an opening set from the band Living Colour.

However, the group pulled out of the shows last month (Oct16), citing an "unforeseen conflict", and subsequently announced it was joining Alter Bridge on tour, instead.

The setback has since prompted Glenn to cancel his entire trek, which had been due to promote his new album Resonate, and he took to Twitter on Tuesday (01Nov16) to break the news to fans.

"UK/EUROPEAN TOUR CANCELLED," he declared, before directing fans to his website, where he states: "I am saddened and disappointed that I will not be able to perform for my UK and European fans as I had originally intended. When I partnered with Living Colour to do this tour, I thought we would be able to make something special happen at these shows."

Blaming an "undermining manager" for ruining "what would have been an amazing tour", he adds, "I can't wait to get back to the UK and Europe to bring the new songs of Resonate to my fans overseas."

Glenn's representatives also make it clear Alter Bridge have been long-time friends of the rocker, and had no idea of the drama surrounding Living Colour's double booking.
