Tupelo Honey - Van Morrision
Done at my wedding and everyone on the planet loves Van Morrision.
Allmusic.com’s article on Paul Stookey disagrees. Where are you getting your info from?
“Days like this” Van Morrison
I’ll second “Longer” by Dan Fogelberg:

Chords:
I also like Queen’s “You’re My Best Friend,” but that might prove to be a bit more difficult than you’re looking for. I like the lyrics though:
My nephew-in-law sang To Make You Feel My Love at our wedding and accompanied himself on the guitar. IIRC, it was made famous by Garth Brooks, but was originally written by Bob Dylan. How can you go wrong with that combo?
If you’re going in the Dan Fogelberg direction, I suggest “Since You’ve Asked” which was sung at my wedding 15 years ago.
Yes, but the song was actually written and recorded first by Judy Collins – and it is a wonderful choice for a wedding.
Three days~ Janes Addiction.
Sorry, I just love the song. It probably wouldnt be appropriate.
Not very cool, but very romantic and appropriate: From This Moment by Shania Twain
You Are So Beautiful by Joe Cocker
Baby I’m Yours by Barbara Lewis
Best Thing That Ever Happened to Me by Gladys Knight and the Pips
I’m particularly biased towards Baby I’m Yours. Heard it at the end of a cheesey Horror Film they’d play on ABC called The Midnight Hour (with Wolfman Jack as the DJ). Love that song.
Just remember Superdude no matter what song you pick, it will be the best song ever.
All the best to you and your bride to be

Uh…thanks, but it’s not my wedding. I’m just IN the damn thing.
Me getting married would require me to be able to get a date.
I would go with “Unchained Melody” by the Righteous Brothers.
“Uh…thanks, but it’s not my wedding.”
Pfft! I give you great songs and you pester me with details!!!

Well, I figured I’d save you before you asked me how the honeymoon went.
