Accompaniment track:
Lyrics
The game of “just supposing” is the sweetest game I know
Our dreams are more romantic than the world we see
And if the things we dream about don’t happen to be so
That’s just an unimportant technicality
Refrain (3 times)
We could make believe I love you
Only make believe that you love me
Others find peace of mind in pretending
Couldn’t you? Couldn’t I?
Couldn’t we make believe our lips are blending
In a phantom kiss, or two, or three?
Might as well make believe I love you
For, to tell the truth, I do
Ending
Your pardon I pray, ’twas too much to say
The words that betray my heart
We only pretend, you do not offend
In playing a lover’s part
