It's bad luck to say "good luck" on opening night
If you do, I tell you
It is certain by the curtain
You are through! 
MAX:
Good luck! 
CARMEN:
It's bad luck to say "good luck" on opening night
Once it's said, you are dead
You will get the worst reviews
You've ever read! 
MAX:
Good luck! 
ROGER:
Even at the Comedie-Francaise,
On the opening night they are scared
"Bon chance, mes amis", no one says
The only word you ever hear is... 
ROGER, CARMEN & FRANZ:
Merde! 
MAX:
Good luck, good luck, good luck 
FRANZ:
It's verboten, vishing "luck" on opening night
Take advice, don't think twice
Or your show will surely end
MAX:
Guten lucken. 
CARMEN:
At the famous La Scala in Milan On opening night it's a 
rule
"In boccu lupa" they say with elan
And just for luck they all shout... 
ROGER, CARMEN & FRANZ:
"Bah fongool!" 
LEO:
I got it!
Now I'll never say "good luck" on opening night
That's the rule, I'm no fool!
What do I say, I beg? 
ROGER, CARMEN & FRANZ:
What you say is "break a leg"! 
LEO:
Break a leg? 
ROGER, CARMEN & FRANZ:
Yes, break a leg! 
LEO, ROGER, CARMEN & FRANZ:
If you're clever... 
MAX:
Good luck! 
LEO, ROGER, CARMEN & FRANZ:
You'll endeavour
To never, never, never, never
Ever, ever, ever say...
...on opening night!
