I have not seen Neil in concert, but I would expect he was better 30 years ago than he is now. That has been my experience with older artists — their voice weakens and they don’t have the energy they once did. Alan Jackson was like that; so was Willie Nelson, who sang his hits as a medley instead of giving them the full treatment. Bob Dylan was probably the WORST concert I have ever been to, with his incoherent mumbling and doing songs from his latest album instead of hits.
Two exceptions to this were: Tony Bennett a few years ago — sensational concert with just a four piece backing band and help from his daughter who sang. Kenny Rogers, who was obviously weaker a year or two before his death, and he had to sit on a stool at times (he apologized, but no one cared — he was still Kenny). He also had help with singing, from the mother of the girl singer in Lady A. It was a very good show and glad I attended. But Neil, I think I might pass.
