Berlin To Broadway With Kurt Weill "Jealousy Duet "

Hi! Me and my friend where looking for songs for districts and we found this 30second clip of "Jealousy Duet" from Berlin To Broadway With Kurt Weill. I was just curious if anybody had heard this song and knew anything about it? We really want to do this song as a duet but im just scared to go and buy the song book for 40 bucks and there be something wrong with the song like it being too short or something and then we are stuck lol. I tried looking it up on Itunes and it seems like that is one of the songs it doesn't have so gah lol. thanks for all the help!

It's from THREEPENNY OPERA. I would find a recording of that show to hear the whole song.
