It was played for a long time - but it was not played every week - it was "mothballed" every now & then. Just when you thought it may have been dropped Colin would play it again as an unexpected treat. It was the same for records like George Wydell, Major Harris, Leroy Britten, John Stansbury, Earnest Mosely etc.
BTW Betty Lloyd is just such a brilliant record & evokes so many happy memories for me & all that "last hour" generation from The Highland Room.
