Curious, I checked out the title as listed above on YouTube, and found two performances, one by the CSMTA orchestra, which was as dissonant as some PDQ Bach pieces, but a lot of fun to watch being performed. (I liked the accordion part.) The next selection was a synthesized piano piece, which might have been closer to what Ian was whistling, and I can understand how he sprained his voice box. Anyway, what a fun and delightfully Different piece. Thanks for the lead, and the laughs.

It's a great composition, isn't it?! Thanks for reading! :)

Listening to the Faerie's Aire and Death Waltz on youtube while I write this.
It sounds like a Video Game boss fight background music.
Also your character did the whistling equilivent of flying too high and being burned by the sun.

Something I learned while drawing this page is there's a bit of a rickrolling phenomenon going on where people label "UN Owen Was Her?" as the Death Waltz - the true version sounds like total gibberish and is approximated here: https://www.youtube.com/watch?v=3W5Oo1XMMvY

Ian is truly the whistling Icarus, tho

And he doesn't seem like the type who could keep tight lipped for long.
