I have an answer for this now. A kid in school said it was "Beyer No. 8"Checking that it is the song, and looks to be a collection of Ferdinand Beyer (1803 - 1863). However, some resources say he did not actually compose it?Further reading states that it is known in different countries such as Germany: Der Flohwalzer - The Flea Waltz. That then leads onto this:https://en.wikipedia.org/wiki/Der_Flohwalzerand that describes it as Flea Waltz in most countries but Russia it is Dog Waltz, Bulgaria Cat March, Hungary Donkey March, Czech is Pig Waltz and Japan is Flea Waltz (I Stepped On The Cat).Waltz is a misnomer:"While the German name suggests a waltz, the piece is not one, as it has 2/4 time signature. A waltz is always in triple meter, with a time signature such as 3/4 or 3/8. The 2/4 time signature suggests a polka, but it can also be played as a march."As for the true composer:"The composer is unknown. A book by Eric Baumann attributes the piece to Ferdinand Loh, but this is obviously a joke (F. Loh = Flohflea in German)."
