Hello all.
I've got a question. I'm a huge fan of Sgt. Frog and I've been looking for an instrumental version of the show's first opening, "Ribbit March." My own search has turned up nothing, but I have a feeling it's out there. So, I figured I'd inquire with those more dedicated and knowledgeable than myself.

I was wondering if any such version exists in any form. (Disc, fan-made, etc.) Any help on the matter would be greatly appreciated.

Thank you all so much!
