Any reliable edition

I recorded and submitted Grade 6 today. Yesterday, for reasons, I had a look at TCL’s diploma lists and something interesting caught my eye.

I’ve already more or less decided what I would play for the FTCL/FRSM level provided it is compliant with the time requirements. But I still take a look at the list and what caught my eye on the FTCL list yesterday was that one of the repertoire pieces was the Volodos arrangement of Malaguena by Ernesto Lecuono. It’s a great piece of music, have loved it both as an orchestral piece and as a solo piano piece for a long time. This is the kind of thing that would pique my interest under any normal circumstances. The thing is, I don’t think it’s been published.

I can’t find it on stretta which is my go to source for any published music, it’s not on nkoda which absolutely is not. The only place it is turning up is Musescore. I don’t like their subscription model and anyway, a lot of what is there is transcriptions done by X, retranscribed by way. TCL call for “any reliable edition”.

What is a reliable edition of a transcription done by Volodos, but not published anywhere?
