Lionel Duke, the drummer for the Christians, collapsed on stage from cardiac arrest Sunday, forcing the end of the Liverpool show.

The band confirmed the news on social media that Duke, 58, had been hospitalized, and asked fans to “please send positive vibes his way.”

“Thank you so much to all the many many messages regarding our drummer Lionel Duke who suffered a cardiac arrest while performing at tonights amazing concert ahead of Sting,” the Christians posted. “We are awaiting news from the Heart and Chest hospital at Broad Green and thank the phenomenal team of medics present from On The Waterfront Liverpool team who stepped in so swiftly to help our poor Lionel.”

The band’s manager, Emma Roberts, said Duke had been put in an induced coma after an operation, per the BBC.

The Christians were opening for Sting when Duke collapsed after two songs. According to the report, lead singer Garry Christian called for medical help, and Duke was taken away in an ambulance.

Roberts appeared on stage to give an update to the crowd, announcing that Duke “didn’t have a pulse” but “he’s got one now, we think,” after “four rounds of CPR,” according to the Liverpool Echo.

“We’re really hoping he is going to make it.”
