bit of an odd one but the live footage of Senna's crash and subsequent footage of the medical team working on him, Murrays voice stands out and conveyed immediately just how serious it looked. As a massive Senna fan and being 13 years old, I remember hearing Murray talk and i'm sure he said something not too polite about the TV director showing the helicopter footage from overhead and Senna having chest compressions. I left the house at that point (football match to go and play) knowing it was serious, only later when coming home from playing football did i hear the sad news.
RIP Murray, the voice of Formula One.
