Brand New Heavies - Sometimes COVER?

Hi,

Can anyone tell me if the Brand New Heavies' Sometimes was a cover version of an old disco 12"? I think it is but cannot for the life of me remember by who! The lryics go....

Talkin' 'bout a revolution, or maybe just a change of mind
Working on my constitution, I began to realize
I've been doin' wrong forever, trouble was my favourite game,yeah
Breakin' hearts I tought was so clever
But, I'm the one who got hurt playin'.

I never could see it comin', no
Never could feel it 'til its come and gone
But, all of that don't mean nothin', no
When you're all alone

CHORUS:
Sometimes you gotta do right to be happy
One time you gotta believe in what you feel inside
Sometimes you gotta do right to find happiness
Sometimes, sometimes


ANYONE?
