Yes, Armand Van Helden took the album track "Professional Widow", very soft song, reworked it and made a DJ bootleg only available on vinyl. The major companies loved it and decided to edit his version for remixes maxi singles. That's the reason why the video was made with the help of cuts coming from Tori's past other videos. TORI didn't knew about this AVB version before commercialisation of the maxi.
Similar things happened with tracks from Sarah McLachlan in Canada. The only difference is that she started her folk career and Delerium features at same moment and was completly agree for remixes. She's still interested by both sides of the music, acoustic and dance.
