Yes, I agree, so much has gone. I worked at Ealing to begin with, Lime Grove, TVC, and small outposts in film dept. Then Pebble Mill. Then Bush House. Every one of those buildings has gone, along with so much of the work that went with them.
I’ve just been watching the first episode of a great series about music - For the record- an incomplete history of music. 9 hour long episodes, brilliantly made and inspiring to watch. Is it on the BBC? Sadly not. YouTube. Not the kind of thing the BBC does any more. Really worth a watch.
