You're a beginner or intermediate Dobro player; you know a few tunes such as Cripple Creek, Old Joe Clark, and Fireball Mail. You might have learned the basics of playing, but you may not have played with other people much or at all. You'reat your favorite festival, and you've just come up on a HOT jam session. You'd love to join in, BUT you're afraid that (a) you won't know the tunes, (b) you won't know what to do or how to do it, (c) you'll be embarrassed...
