Gordon in the morning: Mistaken identity

Could there be anything worse than being mistaken for Bruno Mars?

“Some guy at the airport came up to me and went, ‘Hey, Bruno!’

“I was bit taken aback so I just went along with it and started singing Grenade.

“He was none the wiser, although he probably thought I was acting like an idiot.”

Normally, that'd be a terrible person to be mistaken for, but given this was Jamie Cullum, perhaps being mistaken for Bruno Mars might be getting off easy.
