Every time I see that Matthews clip I'm reminded of a bit on SNL by Robert Klein, the comedian ......
Robert Klein: Give me some blues!
[ the SNL Band plays some blue sounds behind Klein, as he repeatedly raises and stomps his right leg to the beat. He raises a harmonica and maintains a rhythm with the band before singing the solo. ]
Robert Klein: [ singing ]
"I can't stop my leg!
I can't stop my leg, babe!
I can't stop my leg!
I can't stop my leg, pretty babe."
[ harmonica ]
"Can you stop my leg?"
[ the band strikes a beat, as Klein stills his leg on the stage ]
"My leg stopped!
Woo-hoo, thank the Lord.
I want to thank the Lord for stoppin' my leg.
Woo-hoo, yeah!"
[ his leg begin stomping again, as the band accompanies the beat ]
"There it goes again!
There, there it goes again!
There, there, there it goes
There it goes again..!"
