Just for the anecdote...
More years ago than I care to remember (even if I could ...), I was an active member of the organising team for our local summer festival (Les Trois Elephants; look it up..?). Ideas for a 'theme' were always in discussion over the winter hiatus; one suggestion I made seemed to strike a note with the others. I had contacts, from a previous job, with purveyors of second-hand pianos in the North of England. They had (and still have...) entire floors of a very large building, heaving with pianos of all sorts, many of which have no value as instruments (wooden frames, you see...), to be had for a song and a penny. My idea was to bring over to France a Tautliner full of pianos (about fifty or so...), build a pyramid as part of the festival decor, and, at a suitable moment, set it alight. Stuffed with adequate preparation (ping-pong balls stuck in the strings, rubber bands, a bit of pyrotechnics...), the blaze would 'play' itself; it was to be recorded, both from outside and from a couple of sacrificial mic's inside.
The budget was accorded (modest enough; the truck cost more than the joannas...), and a few days before the festival, they were delivered. That's when it all went wrong. Seeing these pianos, half of the team, and more onlookers once they heard the news, decided that these 'instruments' were in too good a state, and would grace their homes. Once a distribution of the better looking furniture (for that's what they're classed as, really...) had taken place, there were so few pianos left, it was not worth piling 'em up..! The remaining pieces were scattered around the festival site as ornaments, but the Biggest Blaze of Pianos in the World did not take place.
A shame, really, as I could otherwise have played you the resulting cacophony. I'd especially ordered (and paid extra for...) a player piano, which was to be the summit of the edifice, playing away by itself until things go too hot. Never mind; at least I tried. The festival was, despite not having this show-piece, a great success, and for several more years since, including this year.
