I saw him a year ago in the US and he's still got it. Very enjoyable concert. Also got him to autograph my copy of the jug band's very first album, the one on Vanguard that Tunesmith mentions, I think--there were four Kweskin jug band LPs. It was very influential in the states and initiated a bit of a jug band craze that affected people like John Sebastian who formed the Lovin' Spoonful: "What a Day for a Daydream" is clearly a modern version of a jug band song, and the Rooftop Singers' "Walk Right In" is an actual jug band song from the 1920s. Without Kweskin, those two bands might never have existed.
