"Let your body free" sample

Hello!

Please could your help me to find the original acapella of this sample? :)

"Let your body free" or "Set your body free" "come on"

this vocal sample is on Jason Joy ‎"Free Your Body", Bizarre Inc "Raise me" too, but I would like to know the original and find the acapella. I'm pretty certain the original was from a disco or boogie tune. Can't remember which one though ..

THANKS

I am trying to ID a track with the same sample, please post here if you find out which tune the sample comes from ;)

Cheers,
Matthew
