Coldplay frontman Chris Martin has described Michael Jackson's forthcoming shows at London's O2 Arena as “the biggest comeback since Lazarus”.
Martin also told The Mirror newspaper that like thousands of Jackson's fans he was unable to buy tickets before they sold out.
"I was looking at it on the internet and thought, 'I'd better buy some for myself' and I couldn't. They were totally sold out,” he said.
"To sell out like that is a testament to talent. It is just amazing to sell out 50 shows in one city in a big arena.
"It's the biggest comeback since Lazarus. It's good news - but not for me."
Jackson is scheduled to play 50-nights at London's O2 Arena. All of the gigs, which run into 2010, have already sold out.
Jackson, now 50, has not performed a full concert since he was cleared of child molestation charges in 2005. His last full tour, entitled HIStory, took place in 1996 and '97.
