"Playing Croke Park in 1985 was probably the high point of the Unforgettable Fire tour, because we really had done it. This wasn't a band that was doing OK, this was a band that was topping the charts and had broke America and the world, coming back to play in their home town, in the centre of their city."
- The Edge
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.
