Children's BBC: what's that noise?

A CBBC opening sequence from 1992, in which Andi appears to have left a speaker on with the sound from the control room next door resulting in some nasty feedback. You can hear his countdown in the background too if you listen carefully. Plus a brief accidental glimpse of the arm of Edd's "assistant" at 0:19. All makes for a rather anarchic link what with all the Bitsa-related messing about too! April 1992.
