I got the music from http://gprime.net/images/mariopiano/ . it is one of the game tunes from Super Mario Advance 2, The underwater theme.

I entered the notes the hard way, i do have a USB compatible MIDI keyboard but i can't play it! (Not quite sure why i bought it) I will probably register my free trial BUT... I'm English and I only have GBP (£) would i be able to pay in GBP?
