Harris wrote the poem Slaughter on the Ice about commercial seal hunting in Canada 35 years ago. After learning that the problem is more acute than ever, Harris has now turned the poem into a song, which can be downloaded from the internet. All the proceeds will go to the charity.
Harris says: "When I first saw the graphic images of seals being killed, I was horrified at the needless barbarity. Now the killing is on an even bigger scale, with more than 350,000 animals killed in 2006. "I hope that people will listen to my song and help end this slaughter."
