Interesting, informative and (for the most part) enjoyable. Even the more nausea-inducing snippets (Clannad, U2, Geldof's face shoved into the camera lens, Horslips' drummer, Riverdance) were there as part of the overall "tapestry" and therefore worthy of inclusion.

And as some of you have already said, that clip of the stepdancer at the end was priceless!
