"I put the now-legendary notice up. I think the wording was something like: 'Drummer seeks musicians to form band'. I just thought of it as a group of people coming together to have a bit of fun, it was never anything else. No ideas, no expectations."
- Larry Mullen jr.
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.
