Well, unfortunately I've only got 'Don't Speak' in MIDI format at the moment. I'm due to get a copy of 'Just a Girl' in MIDI format very soon. If anyone has any other ND MIDI files, please email them to me ASAP so that I can post them up here.
Hold down 'Shift' on your keyboard, and left click on the link below to copy the MIDI file to your computers hard disk.
