Craig,

The language is one of the dialects in the Netherlands called 'Drents'.
The song is about an aged man, Gerrit, often walking thru the fields and thinking about his first love who died many years ago.

At the end Gerrit also dies and the brass-march does everyone realize life goes on.
Hope this explains a little the (unexpected) change.
Tnx for your comments Craig.

Any idea what machine did the music ?
