I ought to lodge my grandad's version which I still sing and I'm 70.

There was an old farmer had an old sow
(snort)ow, (raspberry)0w, (whistle) i-diddly-dow
Sussana's a funniful man
(snort)an, (raspberry)an, (whistle) i--diddly dan
Susanna's a funniful man
Sing lassie go rings-oo-ray
Susanna's a funniful man.

Now this old sow had 3 little pigs....i-diddly-digs

These little pigs they all got stuck.....i-diddly-duck

These little pigs they all made good bacon.....i-diddly-dacon

These little pigs they all went to heaven....i-diddly-devon
