These are two of my chorus groups that I'm in. Aren't we amazing?

Fastball's The Way [I'm at the very far right...not always on camera, though]

Bangles' Walk Like an Egyptian and Jason Mraz's You and I Both

MADRIGALS:

Say Love, A Glimpse of Snow and Evergreen, Deep Peace

Your Song, Route 66

EDIT: Here's one from Mane Event 2006-2007. I am on the far right here. This is BEAUTIFUL DISASTER by Kelly Clarkson, and the soloist is AMAZING. Seriously.
