Watch a few Andy Irvine videos.
Does he look like a rock star? Would you hire him?
Is he fun and engaging?
Ok, he’s got a hip look. Not a hair farmer, but solidly hip. Rock star looks?
And he’s got groove for miles, he’s funny, and friendly. Looks like the kind of guy who would help a band light up a room.
Without knowing what the auditioning band is doing, it’s hard to know just how far off the mark the OP video went.
I saved my six string until I knew folks. First impressions, you want a Fender shaped object, 5 strings max, (4 is safer), and a solid grip on the material they play. And make it a fun time, connect and smile. The solemn noodling invites the Spinal Tap remarks.
I think the response was totally tongue in cheek.
