Advertising lives and breathes hype - most people simply ignore it, it's not worh taking too seriously.
i know Imelda, and she would die sooner than claim to be 'queen' of anything, she is a very unassuming and modest person.
But the advert is designed to sell, so it's not going to say "Imelda May is a hot rockabilly star, but not rock and roll, that;s a different sub-genre althogether ..." so they just bump it up, and people that are interested will buy, and those who are not will ignore.
Next week - is Cillit Bang really worth getting that excited about ....?
