Chalky] Thank you! No, it was The Garden Wall and they did an exact reproduction of the Selling England tour. Apart from a slightly dorky 'Peter Gabriel' it was wonderful. I may even go to see them again in a few weeks time when they come to Birmingham. They are Italian - I believe. Recommended - if you like that sort of thing.
and oddly, I recommend it if you don't. I didn't think I did any more, but that early prog rock stuff was written to be performed so seeing it live added a whole new dimension for me. It was like some bizarre historical re-enactment society, but extremely entertaining.
