On the screen grabs you can see the undulating ridgeline of Beacon Hill in the low background (look closely enough and you might be able to make out the older - now defunct - Civil Aviation Department radar dome).
Had the camera panned to the right you would have seen the old TVB studios. TVB was of course created by Sir Run Run Shaw and the studios were based here on Broadcast Drive from 1967 to 1984 when they moved over to Movietown in Clearwater Bay. All of Bruce's Enjoy Yourself Tonight appearances would have been at these studios on Broadcast Drive. Streetview below.
