The Billy Cotton version was far and away my favourite because it had some of the soundtrack – “Hello P for Popsie, hello P for Popsie, start your attack now” – was it actually from the film soundtrack or something recorded in a BBC studio?
I too had the Billy Cotton version – although I thought I’d ordered a proper orchestral version of the theme. The voiceover and ‘explosions’ were quite definitely not from the film! As you might gather, I didn’t like the BC version!
