Looking for a little feedback, we have a gig coming up, we agreed to let a lady from Memphis do a couple of songs to help her career and with time being short we wanted to stick to covers. We're doing two hours outdoors at a festival before Charlie Daniels concert starts. As you can imagine we only want to do things we know. Anyway her guy asked if we knew the nashville numbers and I had to plead ignorant. I did look it up on the web, is this something you guys think we should learn or is this just a local deal for those studio musicians there?? We're only four years on the road but this is my first run in with it. Learn it, or forget it??
