For all you septics that have got it a$$ about face, the Beatles were Scousers, means from Liverpool.
Mick and Keef are from Dartford in Kent and had Souf London accents, Mick later adopted a US southern drawl.
Brian was the brains of the operation until Mick and Keef outed him. He probably wrote a lot of the early stuff and was a musician, way ahead of the other Stones and the Beatles.
Gram Parsons, Ry Cooder and Mick Taylor gave the Stones massive inputs after Brian died and basically created a completely different Rolling Stones.
After listening to the Stones almost everyday for over 50 years I can say that my favourite album is Goat's Head Soup, my favourite track is Down Home Girl or maybe Backstreet Girl.
If you ever get a chance to buy the Stones bootleg Black Album, it's fantastic.
