I have Delicate... on VHS Masher and I am not sure if it was recorded on film or VHS, the quality of the tape was awesome for it's day, I blew more people away with that one tape than any other in the collection.(I am sure it was filmed, I remember they used "Arriflex" cameras for filming the concert, I'll play my tape and see what the credits say.)
If it wasn't filmed then we won't see it upgraded, but that's okay with me, I have copied my tape to DVD so I will always have a copy to play, tapes wearing out over time.
I still like Delicate better than Pulse, both are excellent.
