The key is G, but I think you'll find the chords a bit of a challenge. I'd worked out most of them before realising that they were staring me in the face. I won't get the chance to post them for another 24 hours, so if you'd like the intellectual challenge please have a try. If you'd like a himt or two you can view the score from the MIDI by using NoteWorthy Composer - there are quite a few accidentals in the the second quarter of the tune and it changes to (as I recall) Gm and D Major scales. Good luck, John
