Watch the Yancey in C online guitar lesson by Ton van Bergeijk from Licks to Riffs Guidebook: Blues

Here's a lick I got from Jimmy Yancey, from a 1940 recording of "Cryin' In My Sleep". He was one of great boogie pianists, and easily accessible, as he didn't believe in being flashy by playing fast. He used it when coming out of the V, so from G7 when you're in the key of C.
