I see my mondegreen has resurfaced. It came in two parts - the first was that tape I got which gave the title of the tune as "The bears have got my Daddy" - and then when I asked at the Mudcat the tape wasn't handy, and I remmebered it as "My Daddy's been taken by bears", so adding chaos to the confusion.
Still, I'm sure that back in the days of the Boer War there'd actually have been children who got the Boers and the Bears mixed up in their head.
I can remember in the war (WW II) getting mixed up between Germans and Germs. I think I had the feeling that if you didn't get rid of the Germs by washing it'd mean Hitler might be coming to get you.
