Sebastian Bach unleashed an expletive-laden message to his fans about his former band during a recent solo show in Detroit.

The 56-year-old was performing when he noticed a fan wearing a Skid Row shirt.

“Yeah, that’s the band that kicked me out,” Bach said, which was caught on a YouTube video shared by The Video Vault. “(F-word) (a–holes).”

According to NJ.com, during Bach’s “Child Within the Man” tour Tuesday night, a fan yelled “Skid Row” to which the singer responded.

“I’m fascinated by this shirt right here,” Bach is heard saying. “This is Skid Row with what number singer? Seven? Eight? Nine? What number is that guy? Huh? What number? Is that replacement number seven? Or number eight? Or number nine? And before you say, ‘Well they don’t have nine,’ I can (f-word) name every (f-word) one of them. How do you even wear that? It’s like, ridiculous. Is that the guys from Dragonforce (ZP Theart)? Or (f-word) TNT (Tony Harnell)? Or whatever the (f-word). (F-word) embarrassing.”

Earlier this year, Bach’s revealed to Metal Hammer that he feels like “like a piece of (s-word)” for not reunited with the band.
