I seem to recall there was at least one Commodore 64 program that lets you play music using your 1541 disk drive(s), but I can't remember the name of it. What was it, and more important, will it work the same way on VICE?

It was often referred to as simply "Drive Music". If you Google "1541
Drive Music", you should get started.

Interestingly, you could turn off the computer while the music was
playing. The program was running entirely in the 1541.

Got it. It's a little bit tricky, but it does work in VICE. After the knocking sound (which I assume is meant to sound like a conductor tapping his baton), the emulated C64 will say "ready." and the 1541 will start playing in monotone. In VICE, an extra
step is needed to hear the drive sing -- you need to execute LOAD"*",8,1 as if you were loading a BASIC program. The C64 will accept no other input after that, until you hit the RUN/STOP + RESTORE key combination (which, for me, is emulated by pressing
ESC + PAGE UP).

Now I just wish someone would make the 1541 play the Cheetahmen theme... ;)

Because it's a self-contained computer system, with an own CPU and all
that is needed.

Back in the day, and I wonder how he got this information, a friend with
a C64 and 1541 (myself only had a datasette) was able to load a program
into the 1541. Turning the computer off and on again, the 1541 would load
this program into the C64 and start it, without touching the C64.

It seems unlikely at least with a stock C64. Easy enough with a cart or modified KERNAL.

I can't clearly remember, what he exactly did. Umm, can the 1541 sense
when a connected (stock) C64 is switched on?

Whatever he did, it looked like magic to me.

I think that much is possible but the C64 is master on the bus. Even if
the 1541 started sending data I think the C64 would ignore it.
