I'd give the sun-shine to gaze in your eyes,
I'd give the stars from the brightest of skies,
I'd give the song of the bird on the tree,
For that to me is love's melody.
I'd give the flow'rs from the fairest of bow'rs
If only you, dear, were true,
I'd give the joys of the whole wide world
For one hour of love with you.
