I decided to set myself a challenge and translate it into an English version that you can sing to the same tune. I don't think I did a bad job!
«Oh, perbacco» diceva Tommaso,
«Se mi viene la mosca sul naso
Io di certo qui dir non saprei
In tal caso che cosa farei.
Che ne dite amici miei?
È una cosa che fa pensar,
che fa pensar.»
Ad un tratto la mosca pian piano
Sul nasin di Tommaso posò.
«Povero naso!»
esclamava confuso Tommaso:
Ohilì, Ohilà!
A farsi furbo così imparerà.
"Oh, my goodness" said Ambrose,
"What if that fly came and sat on my nose?
In that instance I couldn't tell you
What on earth I would venture to do.
What's the solution according to you?
It's a thinker and no mistake,
and no mistake."
The fly suddenly chose to repose,
Gracefully perched on the nose of Ambrose.
"Oh my poor nose!"
cried a baffled Ambrose:
Hey here! Hey there!
That'll teach him to think with more flair.
