The Royal Wedding of Prince Charles & Lady Diana Spencer (CBS, 1981)

This is the oldest VHS in terms of an actual recording and is from my grandmother. She says this was the very first time she used the recording feature that could be scheduled. This was filmed on WAGA-TV, which at the time was a CBS affiliate until the switch to FOX in the '90s. Some bits of NBC's Today Show is also in here, mostly at the end. Some parts were taken out due to copyright. This is by far the longest video recorded, at 6 hours, 12 minutes before cuts.
