Can anyone identify the origin of this track?

Not sure the first post is working so I'll try this way ... Can anyone identify the origin of this track? Not sure if it's a genuine demo or if it's a fake. Cheers

Sounds like an instrumental take of Feelings, Feelings.

It´s only "Feeling,feelings" with a "Vocal remover" Tool (cheap software i must say)...

I wasn't sure because some of the instrumentation sounded different and it is in stereo. I thought tracks with vocal removers or inverted phasing used on them came out mono some how.
