I can remember singing this as a kid at school - we did hand motions to it. The chorus went:

Tick-tock, tick-tock went the funny old clock,
And the little old mill went round and round and round
Went the little old mill.

The verses were very simple ie:

A little Dutch boy and a little Dutch Girl
Were sitting on a hill.
Tick-tock etc

Said the little Dutch boy to the little Dutch girl
"Now will you marry me ?"

And finishing:

So the little Dutch boy and the little Dutch girl
Got married on the hill

The mention of HILL makes me think that the author was not ver well aquainted with Dutch topography !
