[Verse: Bernard Cribbins and (Joyce Blair)]
I don't want to hear your promise
For I'm now a doubting Thomas
Your behaviour is an absolute disgrace
(But, Billy!)

If you swore upon a Bible
Then the church would sue for libel
And I'm not too sure they wouldn't win the case
(But, that's silly!)

For I've seen you kissing others
And you tell me they're your brothers
Do you grow them by the bushel or the bail?
(Who, me?)

Or you tell me they're your cousins
You've got cousins by the dozens
And it's mighty strange that everyone's a male
(Well, you see—)

If I'm slower than molasses
It's these rosy coloured glasses
But from now on all my faith and trust is gone
(Oh, no!)
For I've reached a big decision
What I need is better vision
You're not worth the paper that you're written on

You've made your bed of rolling stone
And now the shoe won't fit
You've had your cake and should have known
You'd have to lay in it
And yet

[Chorus: Bernard Cribbins and (Joyce Blair)]
Once in a blue moon
I think you love me
(I often think I'd like to love you)

Once in a blue moon
I think you don't
(It's rather pleasing
To be so teasing)

Once in a blue moon
I think you hate me
(I only hate you
'Cause I love you)

Once in a blue moon
I think you won't
(I'm undecided
I must be guided)
Once in a blue moon
You want to leave me
(I can't imagine
Why I'd leave you)

Once in a blue moon
You're in a whirl
(You set me reeling
With such a feeling)

[Conclusion]
Why this confusion?
(Why this confusion?)
Here's the conclusion:
(Here's the conclusion)
You are my / (I am your)
Once in a blue moon girl

A blue moon girl
