You make a good point Squonk but I'm not sure how enforcable it is (and no, enforcable is not a dictionaried word and neither is dictionaried). Apart from the fact that we'd have to rely on entrants' word, which I have no problem with, I believe that sometimes it is difficult even for an entrant to ascertain how old his tune is.
On two of the past three challenges I've used themes which I've explored long ago already but never actually used in a song. So to say that those themes came to me as I pondered the challenge of the month would be false. What I could say is that, as I pondered the challenge, those themes resurfaced as appropriate to the challenge, which in essence is similar to Hammeron's piece, the only difference is that she has actually made the effort of recording it while I couldn't be bothered and only did so for the challenge.
What I'm saying, through all that babble, is that I like your interpretation and I would also like to see entrants coming up with a tune specifically for the challenge, but I wouldn't discourage participation simply because the tune happens to be an old one. Not sure how to word that into challenge rules.

I think it would be impossible to put it in a rule, but I think we should suggest making new recordings, if it is an idea that you had in the past, good stuff, but the recording should be new.
