Nadine Coyle
Fine on her own, a powerful and distinctive vocalist.
Boyz II Men
Fine on their own, a respected and popular male vocal harmony group of yesteryear.
Take That's 'Back For Good'
Fine on its own, a moving 'n' melodic contemporary classic.
Put all three together
Oh dear.

Don't forget, readers — someone, somewhere thought this would be a good idea. Perhaps it's a joke?
PROPER SONG SHARPISH PLEASE NADINE.
EDIT: YouTube have, perhaps as a public health measure, removed the audio from the above clip. Basically imagine Boyz II Men and Nadine Coyle doing a really bad cover version of 'Back For Good' and you're along the right lines.
