Tony Smith is commercially orientated....
But the band would certainly be in a position to say "no" to a live release.
In Richard Macphail's latest "Radio Rich Pickings" Tony Banks appears not to rule out a future release though....
TS is their manager - so he deals with business options
I believe they all said we don't need a concert film, since they did that plenty of times in the past and the set was not that much different from 2007. Nevertheless, Tony Banks seems to regret not filming the London shows. But in the end there won't be a miracle. Something that wasn't filmed can't be released, simple as that! They certainly won't use the screen-footage.
Only thing possible would be an extended release of the documentary with a full show as an extra disc - since we all know that was filmed.
