@slaw I have seen JCM a few times, you are correct, great entertainer. That Lonesome Jubilee tour was excellent, he was at his peak. The stage set up was one of the most unique setups I have ever seen. There was not a single visible cable or speaker, at all, on the stage and everything was beige (Arnoff's drums, mic stands, risers, everything) and it had a very clean effect of focusing everything on the band.
Saw him a few years later mainly because Son Volt was opening for him, I think it was Straightaways tour but it could have been Wide Swing Tremelo, they were both very good.
