Thirdson,
Re efficacious, is this the Kingdom song that you are referring to? Here goes:
[Chorus:]
We'll drink a drink a drink
To Lily the Pink the Pink the Pink
The saviour of the human race
For she invented medicinal compound
Most efficacious in every case.
Mr. Frears
Had sticky-out ears
And it made him awful shy
And so they gave him medicinal compound
And now he's learning how to fly.
Brother Tony
Was notably bony
He would never eat his meals
And so they gave him medicinal compound
Now they move him round on wheels.
[Chorus]
Old Ebeneezer
Thought he was Julius Caesar
And so they put him in a Home
Where they gave him medicinal compound
And now he's Emperor of Rome.
Johnny Hammer
Had a terrible ss..ss..ss..ss..ss..ss..stammer
He could hardly s..s..say a word
And so they gave him medicinal compound
Now he's seen (but never 'eard)!
[Chorus]
Auntie Millie
Ran willy-nilly
When her legs, they did recede
And so they rubbed on medicinal compound
And now they call her Millipede.
Jennifer Eccles
Had terrible freckles
And the boys all called her names
But she changed with medicinal compound
And now he joins in all their games.
[Chorus]
Lily the Pink, she
Turned to drink, she
Filled up with paraffin inside
and despite her medicinal compound
Sadly Picca-Lily died.
Up to Heaven
Her soul ascended
All the church bells they did ring
She took with her medicinal compound
Hark the herald angels sing.
OoooooooooooooooWeeeeeeeeeeeeeeee'lll...[into Chorus]
Yup, A great assembly song!
Englishman.
