I actually saw The Firm on that tour. If I remember correctly (and I could be wrong), they opened for Deep Purple. Or perhaps that was a separate concert and being that it was over 25 yrs ago, I simply can't recall some things properly anymore. I do remember Page playing a song or two with the bow though, and that was pretty cool. I think he also played one tune (might have been Radioactive) with a beer bottle during the solo.
