i don't think the mistakes detract from his commentary at all. if you watched the race on ITV and listened to the radio for his commentary, then you could see what actually was going on if he made a mistake, and you can forgive him because as Gav said, he's 83. he's lucky to even be active and in relatively good health, never mind attempting to keep up with what's going on in a manic F1 race!
his mistakes are all part of his charm, wereas James should really know better not to make those obvious mistakes like calling someone driver x, when it was really driver y.
his enthusiasm was infectious and he just sounded thrilled at what he was watching. James just sounds like a tit when he starts screaming, just listen to the commentary as Hamilton crossed the line for pole position at Silverstone, for a recent example.
Murray even got so excited, he said "i'll have to stop now, before i lose my voice!"
i switched the radio off when the race was red-flagged cos the went back tot he golf, but i'd have loved him to come back and join Martin for one race, the European GP especially as it was so action-packed.
RIP Jules, never to be forgotten. #KeepFightingMichael
