Blimey, I'm only 17 and I've often fantasised about this:
I'd have Because Of You at the actual service, then at the reception I'd have pretty much everything

- Bat, Anything For Love, Did I say That, and especially CHSIB!!!
On a side note, I'd definitely have Forever Young at my son/daughter's christening or maybe their own marriage reception. I love that song so much - so simple and yet so powerful.
