Good one Rick. I'll have a go...

1. Ricky Scaggs and Kieth Whitley
2. John Duffey and Mike Auldridge
3. Don Reno (I'm not sure he was there long enough to count.)
4. Bill Monroe and the Blue Grass Boys
5. The Bluegrass 45
7. The Geezinslaw Brothers
8. Joe Val and Bill Keith
10. Doc Watson

Whew, that was humbling. I hope you're grading on the curve.
