Actor Ewan Mcgregor is urging fans to raise funds for a hospice in his native Scotland by downloading a charity Christmas song penned by a paralyzed boy.

The Big Fish star has praised the youngster for his vivid imagination and the lengths he went to to pen a story titled The Christmas Gibbons, which was then set to music by family friends.

Adam Bojelian, 12, from Edinburgh, Scotland suffers from cerebral palsy, a condition that causes physical disability, and lost all movement at the age of 10 months. He can only communicate by blinking and composed the poem with the help of his mother who held up a series of words and letters in front of him.

McGregor is a supporter of the Children's Hospice Association Scotland (CHAS) which helps to care for Adam and the song is being sold on iTunes to help raise money for the unit.

The actor says, "I love the idea that Santa is assisted at Christmas by gibbons. It's quite incredible to think that Adam shares his vivid imagination with us through poetry written by blinking. I hope lots of people will download this track at Christmas and help to raise some money for CHAS at such a poignant time of year."
