How do I make a comically large push button that plays music when pressed?

This will hopefully be a prop for the LOST series finale party I will be having in May. I essentially want to build this big button with the fork and knife on it that plays that song when pushed. (I’m simplifying- no fish biscuit and water prize- what am I an engineering genius?) I’d like to somehow maybe use the mechanisms from one of those cheap infomercial push lights and some sort of music player (CD player, mp3 or even cassette). I am, however, mechanically retarded and can’t think of how to do this. If anyone even has a starter idea, I may be able to build on it. Any help will be of value! Thanks.
