Sad news. Alvin Lee is/was one of my all time favorite guitar players. The most underrated guitarist of his generation. I don't think Alvin ever really got the recognition the likes of Clapton, Page, Beck, etc. were given. Ten Years After were one of the great bands of the late 60's/early 70's.
I might pull out 'Recorded Live', crack a cold one & and crank it up in honour of the great man.
I'm shootin' out your lights, bring you eternal night
