Johnny could only sing one note 
And the note he sang was this: aaaahh 
Poor Johnny One Note

At The Zoo lyrics

Cool your jets and calm yourself, 'cause we are almost there.
Don't get lost--those anim
 hear the brass 
Couldn't hear the drum
He was in a class 
By himself, by gum

Always Look On The Bright Side Of Life lyrics

(Written by Monty Python)Some things in life are bad theycan really make you madOther things just make you swear and cursehe flute 

Or the big trombone
Everyone was mute 
Johnny stood alone
Cats and dogs stopped yapping 
Lions in the zoo 
Were all jealous of Johnny's big thrill
Thunderclaps stopped clapping 
Traffic ceased its roar

The Sweetest Freedom lyrics

I know it's time to say "Good-night".
I have no fear of turning out the light.
So I can taste the sweetest freedom
 
Steamwhistles

Sing out with gusto 
And just overwhelm all the crowd 
Aaaahh 

So sing, Johnny One Note out loud 
Sing, Johnny One Note 
Sing - Johnny - One Note - Out loud
