Anybody seen Graham Nash solo acoustic?

Options
Going to see Graham Nash solo acoustic a week from tomorrow. Anybody seen this tour yet? Seen him solo acoustic before? I've seen CSN&Y and CSN several times beginning way back in the 70's I think, and Neil Young solo acoustic (one of my top ten ever shows - and I've seen a lot of shows). Always wanted to see Graham Nash solo (or Crosby & Nash) - but this has been my first opportunity. Any insights would be appreciated.
