Sibelius - Swan of Tuonela

[Martin Cooke]

Does anyone have any info as to where an organ arrangement of this piece may be found, by any chance, please? I would have sworn on a stack of bibles that I had one somewhere but I can't pin it down. There's a piano arrangement on imslp, but has anyone come across on in the Mayhew series, perhaps... or in one of those old Scott albums - (Red, Blue, Orange, Grey etc)? Many thanks. I've been asked to think about playing it after a funeral.
