My wife in fact commented, "What, did they just interview anyone who was available?" But on further research, Dickinson is a big Python fan, as are many big-time musicians. For example, from the documentary we learn that Pink Floyd helped the troupe finance the Holy Grail movie in 1975, and George Harrison did the same for Life of Brian a few years later.
What I didn't know is that one of the last things the late Graham Chapman from Python ever did was to appear in the fairly typical dumb video for Can I Play With Madness off of Maiden's 1988 album Seventh Son of A Seventh Son. Where in the hell was I? Anyway, here ya go:
