I had lunch with a friend on the weekend, and tentatively (mostly because I don't know for sure exactly what we want by way of ceremony yet) whether she might want to sing a Shaker hymn at the wedding. The other 'tentatively' is that she is a trained opera singer, and sometimes has an understandable reluctance to force herself into another style.

"Sure," she said. "I'll find a nice one, if that's what you want. Otherwise, I know a really nice opera piece from [insert name of opera I've not heard of and promptly forgot] that's for a cello and two voices. M* can do the cello part, and my friend V will do the other vocals. She'll do them for free because she's my friend and I'll make her."

"Oh," said I, pushing my luck, "I'm also thinking of doing the flowers myself, but I'll need someone to drive them, and probably other stuff, to the reception venue on the day.
"Done," said my friend.
"Seriously dude, I meant to tell you, whatever you need me to do, I'll do it."**

I love my friends.

* M is another of my oldest friends, and a performance cellist and performance artist. Why, yes, I am the least creative one in my circle, since you ask.
** The only concession my friend asked for was that she not be made to wear black and white performance clothes, and instead be allowed to wear her own choice. Um, not even a concession. So a requirement.
