Which reminds me, as much fun as it was seeing Black 47 live, which I did a half dozen times, their live albums are close to unlistenable.
Also on the Celtic-ish topic, how could I have forgotten the one live album I've probably played more than any other over the past 35 years - a bootleg of what was once the best live band in the world at their 1986 peak - The Live Adventures of The Waterboys. For a bootleg, the sound is great, some of it captured at their legendary Glastonbury show in '86. They cover Dylan, Van Morrison, Patti Smith/Springsteen, and most notably Prince (Purple Rain with the ending solos via Steve Wickham's fiddle). Only thing missing is Karl Wallinger, who split to form World Party just before this tour started.
