The nice 'documentary' about the Dankworths shown a couple of nights ago on BBC4 is repeated on the same programme on Tuesday (tomorrow)It has them talking about their lives and others who have and still work with them talking about them,and old footage of them both on the road alone and together. Its called the legends and I think they are. Another example of people reaching 80 and still working.
Who are Cleo and John? A tad more info about who they are would have been helpful. As it stands they could have been two dogs for all I know! I was around in the 60's but still do not have a clue who they are!
