First check out the post below yours Track 25, it isnt Music For the Masses apparently, but does contain the vocals you describe.
I ID'd floor Federation - Music for the Masses for somebody a while back, it's on One Off Recordings and released in 2 separate 12"s,
Part 1 here...
http://www.discogs.com/release/83590
& Part 2 here...
http://www.discogs.com/release/157208
I have both and would humbly say that Part 2 with Rad Rice & Mr Monday remixes kicks ass over Part 1, although there is only the portion of the vocal which says "Weeee've........" on those mixes; the rest of it.. "got a love" is not there.
From memory none of the mixes have that vocal, which leads me to think it may be Track 25 from the Graham Parke post below yours that you want.
Hope that helps.
