Blondie guitarist Chris Stein announced he’ll be sitting out Blondie‘s upcoming dates due to health issues. Blondie postponed last night’s show (April 14th) at Huntington, New York’s Paramount Theatre.

Stein, who co-wrote most of the band’s classic hits and co-founded the band with ex-girlfriend Debbie Harry, posted on social media: “I’m sad and frustrated to report that I’m not going out with the next bunch of Blondie touring. I’ve been dealing with a dumbass condition called Arterial Fibrillation or AFib which is irregular heartbeats and combined with the meds I take for it I’m too fatigued to deal. I’m still all in with recording and other band projects and I should be out for discussions etc. later on. The band will be great and (the Sex Pistols‘) Glen Matlock will be joining them on bass. That’s it, I’m fine, I’m around here and I love you all.”

He went on to later add: “Yes, (murmur of the heart) this is indeed frustrating cause my brain is working great but my body’s not up to the task of touring now. I’m fine though and I’ll see you around regardless.”

Blondie kicks off their UK tour on April 22nd at Glasgow, Scotland’s SSE Hydro.
