Motorhead icon Lemmy Kilmister told fans at Wacken that doctors had told him it was time to retire just minuted before he cut their festival appearance short.
The veteran frontman disappeared 35 minutes into what was supposed to be a 70-minute show, still suffering after-effects from a haematoma which forced the band to cancel several European gigs last month.
BraveWords say Lemmy admitted to the fans at the music festival that the experts had advised him to quit, but he added: "We'll have to see about that."
His friend Slash visited him recently and later tweeted: "He's doing well. There's been a lot of rumours but he's in good shape, and finishing Motorhead record now."
Black Sabbath axeman Tony Iommi, who's suffered his own health issues in recent years after being diagnosed with cancer in 2011, sent a public message to Lemmy in which he said: "Wishing you a speedy recovery. Best wishes, Tony."
Motorhead released a statement earlier this week after the Wacken call-off, saying: "The show had to go on because that's how Lemmy rolls. Even though he was not 100% fit, he refused to feel he was letting the 85,000 fans down. They kicked ass for a shortened, but powerful, set befor, Lemmy finally realised he might have bitten off a little more than he could chew.
"Once he fully recharges Motorhead will be back don't you worry!"
