I've seen the videographer 'redo' the vows for a couple of weddings...
If you do, you can hope the couple separates by the time the 'proofs' are ready...
Over the years that the Wife was doing weddings, some number of couples, maybe about 5 or 6, had separated by the time the proof books were done... which for the Wife did take a 'long time', like 1-2 months, since she typically shot about 1500 images... but anyway... I think the quickest separation was about 2 weeks... these sorts of people should have gone to Las Vegas...
Good reason that event professionals get the money before the ceremony!!
