We& #39;re now listening to Mariah Carey& #39;s version of O Come, All Ye Faithful in the Clive Palmer/Twisted Sister face-off. This is amazing.

So, the expert for Clive Palmer has suggested that Mariah& #39;s cover of O Come, All Ye Faithful is actually "more varied" from the classic version of the carol than Twisted Sister& #39;s We& #39;re Not Gonna Take It.

He says he is not talking in "superficial" terms but in terms of "melodic contour". But Universal Music& #39;s expert says Mariah& #39;s cover keeps the melody of O Come, All Ye Faithful intact but "it& #39;s sort of encrusted with embellishments", rather like "barnacles" on a boat& #39;s hull (!)
