F1 and the early BTCC coverage. I found Murray alright personally, wasn't annoying and made it funny at times as it needed an injection to liven it up! It'll be a poorer place without him as he is getting on a bit.
Dear old Murray. Some of his predictions had a habit of turning into curses. I remember some rally-cross from Lydden Hill a long while ago. As the camera followed the race leader, Murray said something like "All he's got to do is hang on to this last bend" followed by a long pause as the camera cut to a picture of the car now on its roof with wheels flailing madly in the air. "He'll have trouble getting out of THAT one!" says Murray.
Some of his anecdotes got a bit repetitive. I've lost count of the number of times he reminded us, when something unpredictable happened, "F1 is IF spelled backwards".
