Don't Forget Tonight, Tomorrow lyrics

Dont forget tonight tomorrow though we may be far apart,
If you forget tonight tomorrow,
Youll leave me with a broken heart.
Are your kisses only mine tomorrow,
Say you love me and you will be true.
And dont forget tonight tomorrow,
Dont forget that Im love with you.
