awesome job mate! loved it, thats a pretty emotional song and your choice to play an instrumental was probably a good one as you would have had everyone in tears, probably yourself included.
man i remember playing knocking on heavens door and altering the lyrics for my 16 dog that i was about to put to sleep and ended up a blubering mess
let alone doing it for a friend, they would have loved your version though as I did!
thanks for sharing
