I was at the Hammersmith show as well. Good stuff! Getting a bit used to HCE in its entirety now though.
Also in attendance: Steve Rothery, Pete Trewavas, Jakko Jaksyzk, David Cross, Al Murray (a huge prog fan who used to come see my Genesis tribute band back in the day). I was in the middle of row K and there were about a dozen unused seats in front of me across three or four rows. Shame, despite the uncluttered view I had.
