One third of Emerson, Lake & Palmer, Greg Lake, wrote I Believe In Father Christmas as a protest against the commercialisation of Christmas. The original accompanying video was criticised for containing shots of the Vietnam War - not light-hearted enough for MTV or VH1’s Mega Xmas Countdown, presumably.
"Difficult one again. Slade's Merry Xmas Everybody, Wizard's I wish It Could Be Xmas Everyday, Nat King Cole Merry Xmas To You, John Lennon Happy Xmas (War Is Over), Greg Lake’s I Believe In Father Christmas, the ubiquitous Band Aid…" (Thanks, bbcoz)
"I increasingly can't stand most Christmas music, but the Greg Lake one is great, and In Dulci Jubilo by Mike Oldfield (because of the kick-ass guitar solo)." (Thanks, BucketheadRules)
"I Believe in Father Christmas - Greg Lake In Dulci Jubilo - Mike Oldfield White Christmas Excellent. If one of these doesn't win there is no justice in the world." (Thanks, BucketheadRules)
"Greg Lake - I Believe In Father Christmas: a) His voice sounding better than anything he sang with ELP. b) His 12-string playing. c) It just sounds like Christmas!!!" (Thanks, suityou316)
