What is the significance of The Anvil in order to warrant a two night engagement is what I was getting at Mike ?
Two nights at the Albert Hall plus two separate nights in Liverpool are quite understandable,public demand for tickets and an above average appreciation of the band by real Floyd fans. Basingstoke ? is it the centre of the Floyd universe (or pretensions so too be ?)
Basingstoke is not so wonderfully far from Beaulieu and after the success of the shows there in past years perhaps those that decide these things are of the opinion that there is sufficient interest to justify the 2 nights at The Anvil. The next nearest venues on the forthcoming tour are at Portsmouth and Bournemouth I think, neither of which is that close to Basingstoke.
