It's a little late to post something about a Christmas gig  
But I just got my copy from CD.
Here's a song our drum ensemble (three guys) did with the Mile Hi Choir this past Christmas. We used 2 djuns, 2 bells, 2 shakers, 1 Twinchin (Kponlogo), and 1 djembe.

FYI, as of 7/22, I took it off my website as it was 6 MB and I needed the space,, sorry!

Anyone played with a choral arrangement?

Off and on since about 1984 (drum set, tympani, misc. percussion). It's mostly been seasonal stuff like Christmas and Easter.  The most difficult thing about it I've found, is that often the choir is singing so far behind the beat that it's hard not to follow them.  And that only makes it worse 'cause they slow down even more.  It took me awhile to learn to tune them out and follow the director.

Yep,, I agree!
This is our largest paying performance, so we make sure we get it right with weeks of practice! And we're probably a shoe-in for next year. It's not a problem for us getting the chops to fit with the choir as the director is very professional - and so is the choir.
But, we have to grind our teeth through the whole performance night as we're the "token bad boys". The choir folk sort of whisper amongst themselves and avoid contact with us. The audience is mostly stuffy and uptight. They have an in-house barratone special solo guy that's an egotistical a-hole who sounds like a dying cow which just hurts our ears.  
Obviously it's not all that bad though. Some of the choir and audience give us really nice feedback, and we walk out with a bunch of money..  

Sterotypes....Sheesh, I can barely type in mono

Ha-ha
Loading out one night, our keyboard player bangs his hand on the side of the trailer door. I ask "oh, did you hurt your playing finger?"
Shoulda seen the slow burn
