"Filming Red Rocks cost us thirty grand. That was all the money we'd make. This was the first tour we were going to make any money at all, and this is where we put it, so there was a lot riding on that night."
- Bono on filming Red Rocks
In the live performance of 'The Electric Co.' from 1983's Under A Blood Red Sky, Bono sang a snippet of Stephen Sondheim's 'Send In The Clowns'. U2 had failed to get permission for this 27-second snippet and later agreed to pay a $50,000 penalty as well as removing the snippet from later pressings.
