Video!
If that is a request I'm afraid people didn't video weddings in 1990. Mainly because VCRs were the size of an outside broadcast unit. But then mine was the only car with a fitted mobile telephone in it and that was the size of a brick with a huge box of tricks hidden in the boot.
To make it clear when I say mine was the only car etc ~ I mean the only car with a mobile phone at that wedding.
