OK, a little late ... the magic needs more spare time
Since it comes from an Australian prod containing all the entries for an Oz party, I figure it's definitely not by Bass. However, correct credit is only this picture where you can select musics. No text, in this prod, refer to a 'Airwalk' anywhere. So, I've set up an Australian Airwalk and linked the music to this author. Maybe we'll find information over time.
thanks for the tip.
