My status as a serious researcher of weighty topics has just led me to look up the 1970s Yorkshire TV children's show Animal Kwackers on Wikipedia. What I found knocked me sideways. The original Bongo was, believe it or not, Geoff Nicholls, the lugubrious Northern drum tutor on Rockschool. Now, I watched the whole run of Rockschool on BBC2 back in the day, and my main memory is of lusting after Nicholls' rather lovely green Yamaha 9000 kit. At no point do I remember him explaining the whys and wherefores of providing a solid backbeat while wearing an outsize dog suit. Nor do I recall Deidre Cartwright explaining how to grip a tremolo arm firmly while wearing a nylon lion's paw, or Henry Thomas showing how to play slap bass without opposable thumbs. The producers missed a trick there, I reckon.
