I did a search a while back for this song also with no luck. Your best bet is to check ebay frequently for the Ulta Zone tab. book that was released in Japan. It's the only one that has Selfless love included. Good luck!
Same problem here man, however within some months I will ask Tom Trapp (works with steve in transcribing world etc) to transcribe it for me (give me the chords etc) so I can finally play it, I love the song:)
