anyone have any idea of the original source of the vocal? because its heard plain as day on the jazz'n'groove track "love each other" on playtime records back in 1993, so obviously the vocals could not have been recorded in 1995.

You are right, Jazz-N-Groove (also sampled the source for their "Into My Life" track on Raw Flava E.P. Vol. No.1), Happy Clappers & Celvin Rotane all sampled from "The K London Production Club ‎– I Believe"https://www.discogs.com/K-London-Production-Club-The-I-Believe/release/223335The guy who done the chords was a music theory teacher at the London School of Sound around ten years ago. Not sure if he's still there.

I'm not sure if we are supposed to take the Happy Clappers that seriously in terms of dance music contribution, They seem to have ended up as a commercial outfit with a few hits to their name. But the track 'I believe' was another one of those turning points that was reached in 1995. The 'Not Loveland Mix' is a mass appeal radio track that has several feel good verses of "I believe were equal.." lyrics. This in itself merits the success that this track deserves (and has Lovelands distinctive sound all over it!), However take the '12" Master' track (which got the club play), this just has the most catchy piano riff over and over, with the lyrics just cut down to mere samples and you have a monster smash of 1995 that spawned several other copy cat records (some of these also by the Happy Clappers!). This tune would make people almost have fits on the dance floor.
