Some people are allergic to dairy products

Milk and butter and cheese

For some it's red wine and cats' hair

Or eucalyptus trees

Well, none of the above

Are a problem for me

What am I allergic to?

You're just about to see

[Coughing and sniffing throughout]

I'm allergic to choruses

I'm allergic to choruses

I'm allergic to choruses

[Back to normal]

When I'm singing a verse I feel just fine

I'm full of the joys of spring

Nothing is itching or twitching

I can breathe straight out and straight in

It's what happens after that

Makes me feel very weird

It happens very suddenly

And it's very severe

[Coughing again]

I'm allergic to choruses

I'm allergic to choruses

I'm allergic to choruses

[Back to normal]

At least I'm not like that man there

He's allergic to his own chair!

(Help!)
