Gospel choirs

I believe that any artist that can pull off a performance with a gospel choir deserves respect, and has mine.  I hate to beat a dead horse and talk more on here about how much I love Jason Mraz, but his performance on Conan last night inspired this post.  Mr. A-Z performed Live High on Conan last night with a gospel choir, and it was great.  I just tried to find a video to link, but apparently I suck, because I couldn't.  Who else comes to mind when you think of non-gospel performers effectively bringing a gospel choir into their act?  U2, in Ratle and Hum - which was brilliant.  Jay-Z, I think?  Snoop?  It's not just rappers, either, there are plenty of others that I just can't think of because it's Friday night and I've had a few drinks.  Anyway, I love gospel music, but only live.  I mean, by live on TV, I still mean live, but I'm just not into gospel on CD or radio. Anyway, my respect for a musician doubles, if not more, if they're able to perform meaningfully with a gospel choir.  I'm just saying.  If you can find JM's performance on Conan last night, it's worth 5 minutes of your time.
