It is quite an experience to walk the bridge, which is on Northern Ireland, just along a bit from the Giant's Causeway. There's a man with a wind meter at one end: they close the bridge if the wind velocity is over 50mph: the day we went it was about 49! It takes you across to a small rocky island. Scary stuff, wobbly, and so high off the ground!

This part of the song describes it exactly:

One step and two, hold tight, let go
Twenty and four, hold tight, let go
I’m nearly there, let go, let go
