Here are all eight classical tunes from the ZX Spectrum version of the 1985 videogame "Little Computer People" (aka "Pet Person").

Tracks:
1. Léo Delibes - Pizzicato [from Sylvia]
2. Ludwig van Beethoven - Für Elise
3. Unknown, probably Bach
4. Johann Sebastian Bach - Wachet auf, ruft uns die Stimme, Zion hört (BWV 645)
5. Frédéric François Chopin - Waltz Op. 64 (Minute Waltz)
6. Wolfgang Amadeus Mozart - Rondo Alla Turca 
7. Wolfgang Amadeus Mozart - Piano Sonata in C (KV 545)
8. Pachelbel - Canon

If anyone can identify track 3 then PLEASE let me know!

Note that #7 is messed up and the melody and bass become increasingly out of synch as the tune progresses!

Other versions of this game (such as the C64 version) featured better quality music, and more tunes.
