Stowitbelow,
I think you may be getting confused with "Tiny Toons Adventures" - the spin-off TV show, starring baby-sized, junior versions of the famous LT characters. This show, did have lyrics written to the LT them tune, which went like this:
We're tiny, we're toony,
We're all a little looney,
And in this cartoony,
We're invading your TV!
We're comic dispensers,
We crack up all the censors,
On "Tiny Toon Adventures"
Get a dose of comedy!
So here's Acme Acres,
It's a whole wide world apart,
Our home sweet home,
It stands alone,
A cartoon work of art!
The scripts were rejected,
Expect the unexpected
On tiny toon adventures
It's about to start!
They're furry, they're funny,
They're Babs and Buster Bunny,
Montana Max has money,
Elmyra is a pain!
Here's Hamton and Plucky,
Dizzy Devil's yucky,
Furrball's unlucky,
And Gogo is insane!
At Acme Looniversity, we earn our toon degree,
The teaching staff's been getting laughs since 1933!
We're tiny, we're toony,
We're all a little looney,
It's tiny toon adventures,
Come and join the fun!
And now our song is done!
