Earl's court '77

I'm really, really sorry if this has been posted before but I'm too damn lazy to look for it over the other hundredth of topics.
There's so much footage of this live, I wonder if the productions intend to make anything out of it. Does anyone know?

I'm not sure, but I do have this concert on DVD (bootleg)
It's one of my favorites. The picture and sound quality are OK. I am hoping that some day soon they will release a proper version of this.
