Yes, even the animated episodes have Production Notes subtitles 🙂 Interestingly there weren’t any for the animated reconstructions for The Ice Warriors episodes, but still pretty cool they included them for this serial.

The Invasion Episode 1 Screencaps, Part 8

Vaughn: Oh, have you got one of these, young man?
Jamie: No. What is it?
Vaughn: Surely you’ve seen them about. They’re disposable transistor
radios. One of our latest products. Most popular. We’ve sold ten
million in this country alone. Here. Compensation for the treatment you
received from the worthy Packer.
Jamie: Thank you. How does it work? *presses the button, loud music plays*
Doctor: *switching it off* Yes, that’s how you turn it off, Jamie.
