[Esther Trousdale]
Oooh, yeah
Oooh

Little guy slipping on your shoes
Brush your teeth, no more time to lose
Comb your hair, keep it in control
Your mother shouts "it's time to rock 'n' roll"

Concealing your nervous energy
Think of all that opportunity
Say goodbye to everything you know
Wave goodbye to everything

When your old tired body wants to sing
I'll soon forget about everything
Oooh, yeah

Now the world can start to see
Your magic capability within your body
Your tired old body

[Freddie Mercury]
Let's go
When this
When this old tired body 
When this old tired body wants to sing
When this 
When this old tired body 
When this old tired body wants to sing
I love you
Take it

[Esther Trousdale]
Little Freddie, just a boy at school
Played piano, tear up all the rules
Furious, hammer every key
Sing another crazy song for me

Stand on your feet, make it on your own
Find a crowd, establish your control
Little shapes, like patterns in your mind
Melodies so beautiful entwined

When your old tired body wants to sing
I'll soon forget about everything
Yeah

So sing
Yeah

[Freddie Mercury]
One, two, three
When this 
When this old tired body 
When this old tired body wants to sing
Go baby
[Freddie Mercury & Esther Trousdale]
When this (when this)
When this old tired body (when this old tired body)
When this old tired body wants to sing (when this old tired body wants to sing)
