er... invisible women off 'the pleasures of electricity' sounds very close to the main tune of underpass.

also flexidisc 'my face' by john which was given away with smash hits, shares a lot of sounds with 'you were there' on the garden.

finally, not really what you meant but. the vocal on endlessly was sampled for the start of 'ghosts on water' the song that immediately followed it on 'the golden section' (and one of my favourite foxx songs).
