I was just running through these, and, I think they're rather illuminating.

First wedding: Processional: Andres Segovia - Recuerdos de la Alhambra

a track I associate with family ski trips

Recessional: The Verve - Bittersweet Symphony let's not talk about the implications

It should be noted that our vows were "for as long as it works."

Second round: Processional (and this was truly brilliant): Harry Belafonte - Hole in the Bucket (careful what you first fuck to)

Recessional: Chihiro Onitsuka - Innocence

a track I looked up after an ad from Applied Materials
