Havannah gila.
Mazeltov!
Or, are you referring to the Yiddish Trinkt L'chaim?
There's the Julie Andrews song and dance in the link below, for you.
Of course, Julie Andrews was neither German nor Jewish, so, if you find it corny, it's OK.
The Horah is the circular dance which is done to the song - havannah gila.
All the best.
