There's no such artist in the trance world as Yellow Blackbird. It's a typo on the 2005 compilation by Paul van Dyk, The Politics of Dancing 2. There is actually no original mix for the song Superfly either which is another typo. Yellow Blackboard never released an original mix. The mix from Politics of Dancing 2 is Superfly (Andy Moor Remix). So start tagging the song as Yellow Blackboard - Superfly (Andy Moor Remix), thanks.
