Oscar Peterson and Count Basie at the 15:56 mark. Two divergent styles that somehow fit on the stage — like the pianos they’re playing, nestled like gloves with twenty fingers.
Oscar talks about Art Tatum, famed for intimidating other pianists (setting up a nice punchline for Bill), and reveals that he favors a special sort of piano, with more than the usual 88 keys (and what happened the one time that Basie tried to play it. Very funny.)
