We were able to watch Top Of The Pops every Friday lunchtime in the common rooms (before VCRs became common) because Mr Dodds had ‘magically’ recorded it for us the night before!
Most of us owned (or knew someone else who owned) a tape recorder, but the concept of actually recording something from the telly and playing it back in four different locations simultaneously at a later date was like something you’d watched on Tomorrow’s World, but never actually believed could possibly happen.
