Give me a kiss to build a dream on,

Sweetheart, I ask no more than this,

A kiss to build a dream on.

Give me a kiss before you leave me,
   Edim     Cdim      G7             Gdim             G
And my  im - ag - i - na - tion will feed my hungry heart

Leave me one thing before we part

Give me what you alone can give
