Guest, Eliza:
Leadfingers, didn't the song by Roger Miller go,
"England swings like a pendulum do,
Bobbies on bicycles two by two,
Westminster Abbey, the Tower of Big Ben,
The rosy red cheeks of the little children" ?

I recall the lyrics as "Westminster Abbey, The Tower, Big Ben"
So three listings, the Abbey, The Tower (of London) & The bell (or possibly the clock-tower)

Cheers

Nigel
