The song is by Albert King and its called "I'll Play The Blues For You part 1 and 2"(He only played parts 3 and 4 at live shows..) It is on his Greatest Hits CD, which is a FANTASTIC cd if you dig the blues... or you can find it on a House of Blues compilation cd "Essential Blues" its the one with the blue cover... hope this helps... i dont know all the lyrics off hand though... good luck
