Let us lift our glasses now to the very good health of the young couple and let us wish them a long life full of love.

Gargoyle's toast is:
Drei gute Ding: Lieb, trink und sing!
Three good things: Love, drink and sing!
[Lieb, trink, sing are imperatives 2. sing.]
But I wouldn't use it as toast, more as a motto upon a stein, or drinking glass.
