Here's what I know from memory....see how it goes

Believe me if all those endearing young charms Which I gaze on so fondly today Were to fade in a moment and flee from my arms Like fairy dreams fading away Thou wouldst still be adored as this moment thou art Let thy loveliness fade as it will

....I think it can't be sung without Drink to me only..so I'll see what I can do there...

Drink to me only with thine eyes and I will pledge thee mine Or leave a kiss within the cup I will not ask for wine The flower that from the dost ask a drink divine oopps...

I sent thee late a roseate wreath not so much honoring thee But giving it a chance... And thou whereon didst only breathe and givest it back to me Since when it lives and smells I swear not of itself but thee..

..well maybe someone can fill in the blanks....I am a great believer in fragments....
