"I thought of Zooropa at the time as a work of genius. I really thought our pop discipline was matching our experimentation and this was our Sgt Pepper. I was a little wrong about that."
- Bono on the Zooropa album
The title of the song '11 O'Clock Tick Tock' refers to a meeting Bono should have had with a friend but missed. The friend put up a note saying 11 O'Clock Tick Tock.
