I noticed the Sea Dew, and it is a brilliant Mondegreen.

Jimmy Mac used to always sing it as See Ya. Christy made it more of a you sound.

I don't claim any expertise in horse grooming whatsoever, I was just relaying a story that I had heard, could be as accurate as Sea Dew. If I get a chance I'll listen to Jimmy's recorded version again and try to make out whether he said "your claw" or "the claw".
