I'm sure a lot of the more recent footage was on 'Roadies' a few years ago (could be wrong though). That was an excellant BBC rockumentary about the touring behind the scenes. If I remember correctly it was based around one of the tours where they ended up playing the Kerrang Weekender Festival at some holiday camp somewhere.
I don't think it's very likely to see the light of day unless somebody piurs there own money into it. Velv .... will not have another try with the band - they might be interested again?!
