Louis Robinson has posted a great live club audio recording of Diz in fine form to youtube in four parts, first is here: https://www.youtube.com/watch?v=Kl5GZ9c1W_A. It is from Pinner, date is not 1960s as stated but presumably around 1971 since there is a reference to the "new" decimal currency at one point (12 bar blues should now be 5 new bars :) ), also he is with Brillo who did not join him until 1971 or so. Enjoy...
