HSBC Adverts

Does anyone know the name of the music from the HSBC Advert with the Apes, and does anyone know where I could find the Music Box version of Fur Elise, used on the HSBC advert with the Supermodel?

You could get the name by turning the subtitles on..

Well not all adverts include information about the music/song used in it, certainly these adverts do not, and sometimes the information isnt too helpful, the PC World adverts say "Intel Theme" which I know is custom music, but is an example...
