I was going to post a load of rare music videos from the early 80's, but it would have been too time consuming and expensive for it to be worthwhile.
There is a lot of video footage from TV appearances out there that even fans of the bands aren't aware of. It is unlikely to ever be officially released or repeated on TV. Have you seen any videos by The Glove (featuring Robert Smith) or any of the performances by Siouxsie with Robert Smith on Guitar?
Check out my video list
. This is from my own VHS video collection that I recorded in the 80's and recently imported onto my hard drive.
There's someone that's building a goth web site that's going to use some of my clips in the future, but until then there are the clips I posted on the thread I started in "User Submissions" part of the forum.
I'm currently thinking about producing a single DVD with the rarest videos I have and then sell them on eBay.
Good luck with your search for videos on the net, sorry I haven't had the time or money to post mine.
