Q: I'm not talking about the quality of this recording, which as all previous reviewers noted, is excellent but it has been done more cheaply and crudely. Not even that far into listening to 'Live At The Rainbow Theatre', I can find no discernible differences between these two versions aside from a couple of key words on each track (a good thing). So if you already own the earlier edition, you'd be better off getting one because they're just ripping us off.

A: Bad review
