What's the name of that song?

When I was down in London and saw Westminster Abbey, an old song popped into my head.  I couldn't remember all of it... just a stanza.

"Westminster Abbey, the towering Ben, the rosy red cheeks of the little children."

I sang that verse all day and just couldn't fill in anymore of the blanks... I got back to my England home and got on google and typed in the phrase and though I didn't have the verse quite right I was able to find the song - England Swings.

Here is a video for it... I like this version because it shows everything I saw along the river... the London Tower (castle and prison), Tower Bridge, Big Ben, House of Parliament and so much more... great memories.
