Post production seemed to have a problem digitizing the tape too, or maybe they prefer oval dartboards.
The dartboards at the BBC used to deform under the effect of all the BBC tea fumes from the canteen*.
*I used to have a friend who worked as a secretary at the BBC. If we were planning an evening out I'd meet her at the BBC and we'd eat in the canteen before going out. I can't comment on the infamous BBC tea as I never drank any, but the food was good for canteen food, and there was a self-service ice cream counter freezer like you'd find in a Baskin-Robins about 12 feet long.
Yes, the BBC staff were well catered for (pun intended), I've had many a lunch in the TV centre at Wood Lane with the engineers there and met a few celebrities as well.
Similar at ITV on the South Bank as well, I was there once with my boss to look at some problems they were having with lighting controls in a few offices not performing correctly. We were in a lift and who should step in, but Jim Rosenthal and he immediately called my name and started chatting to me like long a last brother. When we got out the building, my boss said to me who was that and how did he know you, I told him who he was, (he was clearly a bit jelly), but I never told him that I also knew his brother, and we used to work together and I also knew his mum.
Funny, but the boss never came out with me anymore after that event, so that was a real winner
