MOTÖRHEAD was forced to cancel its performance at the Monsters Of Rock festival in Brazil earlier today (Saturday, April 25) after the band’s frontman, Lemmy Kilmister, was taken ill. According to local media reports and festival organizers, MOTÖRHEAD‘s appearance was called off a few hours before the band was scheduled to take the stage at Arena Anhembi, São Paulo because was suffering from gastric distress and dehydration. Kilmister is reportedly undergoing tests at a local hospital and is unable to perform at this weekend’s event. As a last-minute replacement for MOTÖRHEAD, the other two members of the band — guitarist Phil Campbell and drummer Mikkey Dee — will take part in a jam session with Andreas Kisser and Derrick Green of SEPULTURA, along with other guests. British metal legends JUDAS PRIEST, who were scheduled to play right after MOTÖRHEAD, will add 30 more minutes to their set as a result of MOTÖRHEAD‘s cancelation. OZZY OSBOURNE will close the first day of the festival, which concludes tomorrow with performances by KISS, MANOWAR, ACCEPT, UNISONIC, YNGWIE MALMSTEEN and STEEL PANTHER. MOTÖRHEAD is scheduled to play in Curitiba, Brazil, on Tuesday (April 28) and in Porto Alegre, also in Brazil, on Thursday (April 30). It is not yet clear if Lemmy‘s latest health woes will affect those shows. Lemmy in 2013 suffered a haematoma (where blood collects outside of a blood vessel), causing the cancelation of a number of the band’s European festival shows. The rocker, who turned 69 years old in December, told Classic Rock he didn’t expect to still be here at 30, “I don’t do regrets,” he said. “Regrets are pointless. It’s too late for regrets. You’ve already done it, haven’t you? You’ve lived your life. No point wishing you could change it. “There are a couple of things I might have done differently, but nothing major; nothing that would have made that much of a difference. “I’m pretty happy with the way things have turned out. I like to think I’ve brought a lot of joy to a lot of people all over the world. I’m true to myself and I’m straight with people.” Asked if his illness in 2013 has made him more aware of his own mortality, Lemmy said: “Death is an inevitability, isn’t it? You become more aware of that when you get to my age. I don’t worry about it. I’m ready for it. When I go, I want to go doing what I do best. If I died tomorrow, I couldn’t complain. It’s been good.”
