In Lonnie's version, after the Gibraltar bit, there's some music hall dialogue:

I say, my dustbin's absolutely full of toadstools! -How do you know it's full? 'Cause there's not mush room inside!! [refrain]

and If tin whistles is made o' tin, what do they make foghorns out of? Oooo Ooooh [refrain]

Dennis

oops! Maybe these bits are from the song on the flip side of the record, "My old man's a dustman" Come to dredge this up [from the late 50s] that's probably where they fit in. Memory ain't what it used to be.
