Lyrics:

Knock knock
Knock knock
Who’s there
Who’s there
Knocked up
Knocked up who?
You there
Join us

[Nurse, spoken]
Mrs Hunterson, the doctor will see you now

[Company]
Welcome to club knocked up

Knock knock
Who’s there?
Precious
Precious who?
Precious little parasite who set its sights on you
Dream come true
Welcome to club knocked up
Welcome to club knocked up
