The Baarmy Sheep of northwest England's Lake District star in a new mix of the old yuletide favourite "Jingle Bells" set to take on the Crazy Frog's version.
The computer-generated frog is among the favourites to scoop the coveted British Christmas number one single crown after his debut outing "Axel F" topped pop charts in 21 countries.
However, the Baarmy Sheep are out to ram the Crazy Frog out of the charts and launched a pre-emptive strike in an attempt to get fans flocking to them first.
The "baa"-filled dance song, recorded and mixed by 27-year-old British record producer Charley Darbishire, was rush-released in mp3 format on the Cumbria Tourist Board's website, a day before the Crazy Frog's "Jingle Bells" hits the airwaves.
"Christmas may be the season of goodwill to all men, but not Crazy Frogs," said tourist board chairman Eric Robson.
"Visitors from all over the world love the Lake District and our sheep, so we're confident people will prefer our version."
The original "Crazy Frog" hit, a bizarre remix of "Axel F", the theme from the 1980s Eddie Murphy movie "Beverley Hills Cop", became a suprise sensation earlier this year, becoming the first ringtone to top the British charts, remaining there for four weeks.
