I think perhaps we should promote this as an introductory puzzle for newcomers to the Listener. It has thematic answers (which are massively hinted at by the title), a decent missing letters anagram to solve, and a simple find the words end game - the most common ingredients of a proper Listener but with Times level clues and very few odd words (my personal count was two) for a grid of this kind. Karla is to be congratulated for providing a sound introduction to our joyous pastime!
