Talking about Arthur Baker's Club Vocal Mix. Got the US Promo 12" today and there is a very short instrumental bit after what I thought was the end of the mix - compared to the version on Ultra Rare Trax Vol.1
Is this an accident caused by the equipment or does it belong to the mix?

There is a last orchestra bit after one second of silence at the end of the Club Mix, yes, that´s the way it is...

And would you think it' intentional and belongs to the mix or is it an accident?

I think it's intentional...weird indeed, but intentional...In a bizarre way but it has some sense to my ears...
