Query: Worst possible Deep Purple CD

Give them credit, the liner notes say what the band was up against during this concert - a half paralyzed Tommy Bolin due to drugs. But this is...that should never have been released. John Lord does a very boring solo, Glenn Hughes voice repeatedly cracks, there's virtually no guitar player, and no matter how good they are here - David Coverdale, Ian Paice and Jon Lord just can't carry the show. I never bought a CD that I genuinely felt ... before this one. Very sad...
