I am sure the song has traveled and evolved but here is the 1940's
''pop'' version from the East end of London. (I will ask if there were other verses).

Last Sundy aternoon for tea, I fort I'd av a luxury, I stopped by poor old muver Brinkles, bought me self a pennyworth o' Winkles.
Took em ome, stuck em on a plate, as appy as can be.... I'd ardly turned me back on them when all the family was...

Picking all the fat ones out, picking all the fat ones out, there was the missus and 7 little kids all picking all the fat ones out.
All the fat ones gorn, ow I did scream and shout, there was the Missus
and seven little kids, picking all the fat ones out.
