ABBA Super Trouper - Rare early mix (filtered vocals) HD

This is an early mix of the song which to my knowledge was unknown until very recently (check the link below). I've filtered the center stage audio revealing a lot of interesting vocal layers that are buried in the final mix. The clicks and the gap heard in the first verse are due to a damaged source.
