I kind of prefer this other video by LGR on the subject of monkey island title music through different PC music devices. It does not have the commodore 64 as it only cover PC, it more devices and illustrate how different the same song is on same platform with different hardware.
Yeah, that really shows how much effort they (had to) put into supporting the variety of PC sound cards - although by the 90s most (affordable) cards were (or claimed to be) "AdLib/SoundBlaster-compatible". But I still like the video I posted better - I mean, there were (and partly still are) other systems out there than the PC, let's not forget that! And I originally played Monkey Island on the Amiga, so that version has a special place in my heart...
