I remember Jerry recounting to me with total delight the game he and Mose Allison played that Mose might have called “I bet you I can fake you out of the downbeat.” When Mose played a familiar song he usually stretched out the final phrase for effect. “Your mouth is working………………………overtime”. He never faked Jerry out. Jerry might have been laughing during the game, but he always hit it ….perfectly! Basically Mose had a tell (as poker players would say)
