Serious Paul McCartney fans never really took to ‘Wonderful Christmastime’ but for the rest of us it always has the makings of a festive party starter with those cheesy synths long establishing themselves as a yuletide signature sound. Must be said though that the ditty has rarely been given the cover treatment but a new one for 2013 could be strong enough to get even the aforementioned unbelievers on board. With Straight No Chaser offering the acapella backdrop (this version relies purely on vocal utterances, no music whatsover was added!) McCartney himself has climbed aboard to add his own vocals. And the results are stunning with this new version rivalling the glorious beast that was the original. 'Wonderful Christmastime' can be found on Straight No Chaser’s ‘Under the Influence: Holiday Edition’ which came out at the end of October and featured collaborations with the likes of Cee Lo Green and Otis Reading (posthumously of course).
