that way or is there a way to get the vocals off the mixed single
(photoshop for sound ?). Or even earlier, something like Rappers
Delight, where there wasn't computer jiggery pokery and they apparently
didn't have permission to use the sample (maybe just loop a bit without
vocals?).

If a stereo recording, phase reversing one channel at filtered frequencies
might remove most of the vocal - or someone may have made a prog to do
this digitally - but it's unlikely to leave the backing totally untouched.

Right. Next I'll be asking why the vocals get louder when you make stereo
mono (it must be true, I heard it on Radio 2 the other day when someone was
talking about Dock of the Bay).

If the vocal is in fact mono as most are on a stereo recording (apart from
the reverb) it shouldn't make any difference. However, there is likely to
be more in the way of 'phasey' FX applied to some backing instruments to
make them sound bigger, and this will cancel in mono. I'll see if I can
dig out Dock of the Bay and have a play, and try and analyse it.

** Where there is a central vocal on a stereo recording and the other
sounds are uncorrelated between L and R channels - the vocal will
appear 6 dB louder in the L plus R sum signal while the sum of the
uncorrelated sounds will be only 3 dB louder, on average. So the vocal
signal gains 3 dB.

However, when the same recording is played by a pair of stereo speakers, the
exact same summation occurs in the air so the relative vocal to instrumental
balance remains unchanged to a listener.
