>Why is the word "gooly" causing that song to be banned? Is it >because it sounds like "coolie"?

Gooly is banned (I assume) because it makes small boy scouts snigger and giggle (goolie being a UK English slang word for testicle)...

In the UK guiding movement (this is sliding off topic slightly!) we have Rainbows (tiny girls) then Brownies (7 - 10/11 years old) and then Guides (10/11 - teens) and Rangers (16/17+).

Brown Owl is the big boss of the Brownies, an adult leader rather than one of the kids Our troop had three leaders (we must have been very unruly):

Brown Owl
Snowy Owl
Tawny Owl

Then two Pack Leaders (older guides) to help out.

and the Brownies are in Sixes with a Sixer and Seconder each. My history teacher used to accuse us of being a pseudo military organisation...I think he had a point!
