Five, described.

1. Gillian Welch - The Way The Whole Thing Ends. A slow sleepy tune. It's nice, pleasant. Maybe a touch long.
2. Grateful Dead - Ripple. A slow sleepy tune. It's nice, pleasant. Maybe a touch long.
3. David Grisman & Tony Rice - Wildwood Flower. Bluegrass standard, instrumental. Not found on YouTube.
4. Bill Monroe et al - I Saw The Light. Another bluegrass/gospel standard. Though it's a Hank Williams tune, for me, this is the definitive version.
5. Jungle Brothers - Straight Out of The Jungle. I was a little worried that my latest sync had somehow filled my iPod with country music.

Is there anything you'd like to share with the class?
