I saw "The Machine" back in 1992, thinking I would never have the chance to see the real thing (luckily PF toured for TDB and I saw them twice -- and no cracks about PF Music Ltd (1987) not being the "real thing.") The lead singer had some foot pedal-thing that made his voice sound like Roger or Dave (I think he was a "natural" Dave, though). "The Machine" did some lesser-played stuff: Free Four, Astronomy Domine, Breathe, Dogs, Pigs on the Wing I & II, etc. The lead guitarist didn't wander much from Gilmour's work, although he did play Dave's DSoT solo for CN. All-in-all a decent show.
