I always liked ELO BlueMeanie and yes they were a very big band , but i remember at the time a lot of people turned there nose up if you said you were a fan , poor man's Beatles thats what one of my friends used to call them.
And although i think they are getting some respect now , there still not spoken of in the same breath as Pink Floyd ,Led Zeppelin who i think they are as good as,  popular yes but they don't sit at the top table , were they should be in my opinion .
