Sorry to hear Diz is unwell. I remember him well from my days at the Troubador. Great Jazz man. Booked him at Lincoln Folk Club when I ran it in the sixties. Well I remember be arrived in Lincoln in a battered Rolls Royce. The next day he topped up to go back to London had to put a gallon of oil in. I think he might have had to put in more oil than petrol. Great performing monologues, especially "The Battle of Hastings".
