Pop Quiz! (Desperately seeking...)

Right, Nick reminded me of a song last night, and now it's going to drive me mad until I find it.
I suspect it's sung by Martina Topley-Bird (the female singer from Tricky's early albums), but I'm not sure.
The song itself is, again from memory, a fairly gentle trip-hop-esque track, with dreamlike female vocals slowly over it.
The verses mainly follow the pattern of mentioning a number and then what it is, like " is the telephone number of a lonely one; is the serial number of my gun".

I'm failing to find anything via Google searches for lyrics though.


Help me Indie-Wan, you're my only hope!
