Here’s my version of this type of thing - when a band I’m in wants to do a song that requires most of the learning and/or programming be done by me…and, inevitably, after a whole lot of prep on my part, when we do try to play it live (with no rehearsal), they’re nowhere near as prepared as I am, and we end up only doing it once or twice.
A couple examples would be Kashmir and Won’t Get Fooled Again. The latter was really annoying for me - I had to have the organ sound triggered by LFO when I was the only one playing, then switch to manual 8th notes modulated by a phaser when the band was playing because our drummer refused to play with a click.
However, the worst one was having a club owner who was friends with our singer request that we learn to play Pink Floyd’s Dogs. Waaaay too long for a non-Floyd bar gig, way too much keyboard programming and not a lot of effort required from the other members…so, I’d have had to spend a bunch of time programming sounds for a 20 min song so we could play it at one gig because one guy requested it…
… and I even already knew how to play it end to end acoustic guitar.
I refused. Hilarity ensued. 😒
I even offered to do an unplugged version, but noooooo - they wanted an “authentic” version.🙄
