If I weren't behind this firewall, I would post a link to Radiohead's "Punchup at a Wedding." One of my favorite songs.
I love Radiohead! “Too Many Sandwiches” by the Stereophonics is my favorite wedding song— really seemed to capture most of the weddings I was a part of at the time. I think my wife is glad that we are now out of the wedding demographic if only because I don’t (badly) sing “you bought a sequin dress for a chicken breast, the discos late and he’s overpaid tonight” throughout the buildup to the event.
