See if you can answer the following multiple-choice question: Who had a hit UK album with Born To Do It, released in 2000?

Most pop music fans would be able to identify the correct answer (D) fairly easily. Born To Do It was a huge album which spawned several hit singles.

But former British Army major Charles Ingram had no idea who Craig David was when he was asked this as a contestant on ITV gameshow Who Wants To Be A Millionaire? in 2001.

He admitted as much as he mulled over the possible answers to the £32,000 question.

"I think it's A1," he told host Chris Tarrant. "I've never heard of Craig David, to be honest. Coldplay I've never heard of. I think I'll go for A1."

So it was a surprise to everyone when he suddenly changed his mind and opted for Craig David as his final answer, seemingly for no logical reason.

It was an even bigger surprise when he got all his subsequent answers correct as well, ultimately winning the show's £1m jackpot.
