The incomparable Jennifer Hudson sings the roof off One Night Only in her appearance on The Tonight Show.

ONE NIGHT ONLY
You want all my love and my devotion
You want my loving soul right on the line
I have no doubt that I could love you forever
The only trouble is, you really don’t have the time

Chorus
You’ve got one night only, one night only
That’s all you have to spare
One night only, let’s not pretend to care
One night only, one night only
Come on big baby come on
One night only, we only have ’til dawn

In the morning this feeling will be gone
It has no chance going on
Something so right has got no chance to live
So let’s forget about chances, this one night I will give

Chorus
You’ve got one night only, one night only
Will be the only one
One night only, then you have to run
One night only, one night only
There’s nothing more to say
One night only, words get in the way
One night only, One night only
One night only
