I found it!!
So, I've typed the words out and then came back, did a search for the big effin bee and got the old thread...like, 5 years old!
I posted the words there but will post them here as well hoping that the 2 different spellings may mean that someone can find it easier next time (neither spelling's right, BTW!)

Explanatory start..
There's a cute town called Effen jist outside Edinburgh, jist 800 miles outside Edinburgh…it's in France!
Famous for it's honey so there's an awfie lot of bees

             The BIG EFFEN BEE
             Matt McGinn

"He kept bees in the old town of Effen,
An Effen bee-keeper was he,
And one day this wee Effen bee-keeper
Was stung by a big Effen bee

Now this big Effen bee-keeper's
Wee effen wife for the big Effen polis she ran
For there's nobody can sort out a big Effen bee
Like a big Effen polisman can

Now the big Effen polisman he did his nut
And he ran down the main Effen street
In his haun wis a big Effen bat
He'd big Effen boots oan his feet

Now the polis got hold of this big Effen bee
And he twisted the Effen bee's wings
But this Effen bee got his own back
For this big Effen bee had 2 stings

Now they're baith in the Effen museum
And the Effen folk oaffen come see
The remains of the big Effen polis
Stung to death by the big Effen Bee!
