In Thurman & Hazlewood's "The Gilwell Camp Fire Book" of 1957 (a book of Boy Scout songs), they give the following:

Look at the Brownies
Dancing round toadstools.
Ain't it grand
To be bloomin' well dead?

It has the comment:

"At one time on the banned list as being 'not quite nice', a view we never agreed with. You don't have to sing it, but we don't see why it should be thought offensive. If there was ever a neat phrase in a Scout comedy song it is 'Look at the Brownies dancing round toadstools.'
