Query: Ack!

Oh my god, what were they thinking releasing this?!? Heep were (and still are) a killer live band (listen to any of several recordings from "Live 1973" to the recent "Acoustically Driven" for good examples), but this has to be one of the worst live CDs ever recorded; the sound is muddled, and singer David Byron (whose alcoholism eventually killed him) is so obviously and thoroughly plastered that it's a wonder he could stand, much less attempt to sing. Avoid this one at all costs.
