You just gave me a great idea for if I ever get to to start the Stevie Winwood thread, Slak.
Did he ever go by Stevie?
I thought so; could be wrong.
I know that he was only sixteen when he recorded "Gimme' Some Lovin'" with the Spencer Davis Group. I suspect he was getting laid when he was 14, so for what it's worth, I could see him going by it. Tonks?
I wasn't getting laid when I was fourteen, and even if I had been I have no idea if I'd have called myself Stevie because of it. So, I can't really help, mate.
