I've sung this song for years and never come across anyone else who knew it. Now it seems we all do!!

I've only ever done five verses (quite long enough for performance purposes!) but with the addition of 'street cries' at the end of each chorus. I got these (and indeed the whole song) from the singing of (as they say) John Foreman, probably when I was a student in about 1978.

The chorus to the first three verses therefore goes:
Doodle-dee doodle-dum,
Ri-dum-doodle-ay
Sprats! (pronounced "Sper-aaaaats!")

...and then after Mr Lillywhite Sand is introduced his cry is added: "Do yer want' any lillywhite sand?" (going down a fifth (I think) on the last word). It starts about halfway through 'sprats'.

The gentlemen are invited to sing this while the ladies carry on with their sprats.   The overall effect is quite, er, interesting!

Stop me and ask me to sing it (if you must!).
