Worth restoring?

Some time ago, Sikke uploaded an 18 min. long video of the famous David Wigg 1985 Interview of Freddie Mercury. Since it's the only available source, I wanted to fix it as much as I can, so here's what I've done so far, but I'm not sure if it's even worth it. What do you guys think?

I haven't used any cleaning methods yet, other than doing some color correction where I reduced a lot of redness to it.

Uhm nope

Maybe if you can change the colours a bit
And give them a different wardrobe and hairstyle
And synchronise with other voices, like the voice of spongbob

what video program to use for cleaning ? or color correction?
