List of remixes that add extra vocals to the track (not counting rap remixes)

Razormaid are edits/bootlegs though

That's what I always thought too, but a couple of years ago I bought a Razormaid comp which included their remix of Telex's "Raised by Snakes", and it has normal vocals instead of the vocoderised vocals of the original version. So they must've had access to the original tapes for that one at least.

The 12" remix of 'La Femme Accident' by Orchestral Manoeuvres in the Dark has some extra vocals on there which aren't in the 7"/album version. Having said that, it sounds like the whole thing is re-sung to me.
