Cooper makes shock stage appearance
Alice Cooper was a surprise guest on stage for West End hit Rock Of Ages The Musical.
The US rock veteran made his one-off appearance to mark the 40th anniversary of his hit single School's Out topping the chart in the UK.
He and his band's outrageous performances at the time led clean-up campaigner Mary Whitehouse to call for the video to be banned while one MP tried to stop him appearing in the UK.
Alice joined cast members including Shayne Ward - who plays Stacee Jaxx - for the performance at the Shaftesbury Theatre.
The 64-year-old, whose real name is Vincent Furnier, has been playing live in the UK and is promoting his forthcoming Halloween Night Of Fear III UK tour.
He revealed he enjoyed crashing the musical.
"It's different because it's not my show so you do feel like a bit of an intruder, but at the same time it complements the show so much," he said.
Alice also reflected on the enduring popularity of School's Out, which first became a success in London despite - or because of - calls to ban his group's concerts due to their shocking theatrics inspired by horror movies.
"I knew it was going to be a hit," he said. But, he added: "I did not know it was going to have the longevity, it was going to be the national anthem. I don't think anybody does. I think when Slade wrote Merry Christmas Everyone they didn't know that that was going to be the personification of the Christmas song, or when The Who wrote My Generation, every generation would relate to those lyrics. I think that's what happened with School's Out."
