I remember them as those "Live"-rip-offs from the horrible "Rare Live" - presented by Doro as "rehearsal" footage, those clips are nothing more than mimed promo-clips, the first (bright) apparently from a TV-Studio, the second (darker) perhaps from their rehearsal site at the time, but definitely not live as Doro wanted us to believe.
But I too don't know for what purpose exactly they were recorded, maybe Top of the Pops ?
