Have you seen this old documentary about their road crew?

No, but after watching it... I would not want to be a road crew man, too much hard work!

I think my sister bought Script and that was my first exposure to Marillion.

Your sister has great taste, it seems she was your trigger for the band. Now what made you pick up that 12', flip it and play the 'B' side. I never did when I bought singles?
