Just saw them the other night in Tokyo. Very close to what was reported from Glasgow. They seem to have it down by now, and really appreciated the warm welcome from the sold-out Japanese audience, which apparently had never seen the original members perform. Neither had I (together) in fact, and it really exceeded my (admittedly not too high) expectations.
Like its been said, the pedigree of the members could lead to some wrong conclusions about their music, but accessable it was, and the playing really quite good, especially my personal hero, Mr. Palmer-san. Also they did play for 2 hours, and lets face it, how many more chances will we have to see some of the founding fathers of prog?
