The best horror movie soundtrack of all time, ever, as they say in the adverts, was composed by someone who, as far as I can tell, had never done one before and never did again, though he did do other film work and lots of radio and television. David Lee (who is on IMDB as David Lee(IV) if I remember correctly, and on ISIRTA as "Dave Lee and the boys") produced a stonker of a score for Roger Corman's Masque Of The Red Death, and I now have it on my computer after forty years of searching.
I've always said I wouldn't bother with a funeral, as and when the time came; just wrap me in a bin bag and carry me in a wheelbarrow to the nearest field in need of fertiliser. But if I could have
this music, then I think some small ceremony might be nice. The mourners, dressed as scantily as decency would allow and spattered with red body paint, would dance solemnly and sinuously around the coffin as, borne by six bearers wearing monastic robes in bright colours, it passed through the streets of Westbury to the cemetery. The officiating cleric, of course, would have to wear red.
But I expect the locals would kick up some sort of fuss, so probably best stick to the original plan.
