Joining! Watched all three that had recorded while I was away, last night.
I too got very confused with her husband and co-singer they looked so similar. Also got vaguely confused with Watty and the other manager! 
I'm enjoying it so far, although I think I can get a feel for how it will pan out. It's nice to watch a non cop/legal/hospital drama tbh. It's a refreshing context.
They seem to be able to knock out a song at the tip of a Stetson though!
