I would like TMWSIY for the procession part…I don’t think she will agree though, I can only go so far but as a wedding song to dance to i like the ideas!
At Vegas 1993, I watched a couple get married before the show at Sam Boyd Silver Bowl. Jerry came out and played Peggy-O for them. But… Since that’s a Dylan tune…Greatful Dead/Fail.
At my wedding, we introduced the wedding party to “First Tube”. Funny as hell, there was classical music playing when they were announcing the parents, grandparents, etc…
But when they announced wedding party, they kicked into First Tube, and you can see on our video, everyone in the wedding party just start getting down!
And as for other Phish and our wedding, well Drifting and Waste both made appearances in our wedding video. Drifting was in the middle, and the “closing credits” and baby pictures were shown to Waste.
So yeah, to answer the original question, it would have to be BBFCFM!
