Editing Duck Soup (1933 film) (section)

===Original songs by Kalmar and Ruby===
The "Freedonia National Anthem" is used frequently throughout the film, both as vocal and instrumental; the entire song seems to consist of "Hail, Hail, Freedonia, land of the brave and free", contrasting with the final line of ''[[The Star-Spangled Banner]]''. The "Sylvania theme", which sounds vaguely like "[[Rule, Britannia!]]", is also used several times. "When The Clock On The Wall Strikes 10", the first musical number in the film, is part of the same scene as "Just Wait 'Til I Get Through With It",<ref name="filmsite"/> Groucho's song about the laws of his administration. "This Country's Going To War"<ref>TCM [https://www.tcm.com/tcmdb/title/73717/duck-soup Music]</ref> is the final musical ensemble in the film. Technically it is the only musical number in the Marx Brothers' films to feature all four of the brothers. However, in ''[[Monkey Business (1931 film)|Monkey Business]]'', Chico briefly bangs on the piano while the other three play saxophones while eluding their pursuers on an [[ocean liner]].

The introductory scene, showing ducks swimming in a kettle and quacking merrily, is scored with an instrumental medley of the aforementioned songs, and it is also the only scene in the film that has to do with ducks and soup.
