Thank you, especially for that clip of Big Mama Thornton and John Lee Hooker!
What we know as "Rock and Roll" may have started with a bunch of white teenagers in England, such as Keith Richards, Eric Clapton and Pete Townsend, sitting around listening to 78's of Robert Johnson. If anyone was the father of Rock and Roll, it was Johnson. He has also been the most ripped-off artist. A few titles you may know:
Love In Vain
Travelling Riverside Blues
Crossroad Blues
Sweet Home Chicago
Someone found one of his living relatives, and sued the big names who claimed the song for their own.

Things came full circle when some of those who ripped off his songs came together with Buddy Guy, who got Barack Obama to sing "Sweet Home Chicago" at the White House.
