the "camping" song: http://en.wikipedia.org/wiki/Dueling_Banjos
the "end of the world" song: "O Fortuna" from http://en.wikipedia.org/wiki/Carmina_Burana_(Orff)
the "nautical" song: http://en.wikipedia.org/wiki/The_Sailor's_Hornpipe
the "Italian" song: http://en.wikipedia.org/wiki/Tarantella_Napoletana
the "morning" song: "Ranz des Vaches" from http://en.wikipedia.org/wiki/William_Tell_Overture
