Where It Ends Mystery Cache

I'm making a list of all my friends;
I'll keep going until it ends;

We'll form our own ourchestra together;
And play in the grass until stormy weather;

Then maybe we'll enter this deserted house,
playing and playing loudly our Strauss;

On the drums will just be Me-Stew plays sax with Steve,
We'll play on and on-until they all leave!

Then I'll sleep and dream of notes and boats,
And anything else I remember that floats;

When I wake they'll be but two boxes left on the floor,
Only full of the sounds of the night before.
