Thanks Pat for that interesting walk down memory lane.
I remember reading of that event back when I was kid in the early 50's.

Can you remember the first international, live TV telecast? Can you give the

2. network
3. year
4. host of program
5. What two countries were involved? (No it wasn't the with Soviet Union)

I was watching the day this event took place.
