"U2 have had two really rotten fashion phases. One was the October tour, where I had a skunk on my head. The second was The Unforgettable Fire period. You should never draw attention to your legs if you don't have any."
The show where the Red Rocks show was recorded would originally have been postponed due to bad weather, but the band couldn't afford this because they had a film crew over. That is the reason the show happened regardless.
