A name Change ? ?

I've just noticed that the fellow in the Discover Ireland (Dublin) ad on T.T. - has changed his name.
A few months ago, he was Derin. Then he disappeared - now he's come back as Aiden.

Thats nothing,,, a bloke at work (John) had 6 months off work and came back as Tracy.

Obviously not Dick Tracy...

Or Tracy Piggott...
