My dad used to sing this -

Well, I hate to repeat
but I must have meat
for my 'taters and my gravy
So Wilberforce
Get off that horse
and bring him in to lunch

Oh a leg for me
and a loin for you
we can even cook the saddle too
So don't say nay (neigh?)
and ride away
as if you never knew me


Where the heck did this come from? And what's the rest?
