This psychedelic-flavoured advertisement targets the young 'groovy’ baby boomer generation, most of whom were in their late teens or early twenties when this advertisement was made. It matches subliminal advertising techniques – quick inserts of the Crunchie bar and flashes of the word 'Cadbury’ – with strobe aesthetics of a kind you would expect to see in a disco. It is an incredibly atmospheric ad, with another catchy Cadbury’s jingle, and offers a strong example of the way that successful products often align themselves with a desired experience rather than marketing themselves on facts.

The mustachioed dancer is Issi Dye, a 1970s pop star who also hosted and appeared on episodes of TV’s Bandstand (1958–72), Kommotion (1964–67), Go!! (1964–67) and Happening 70 (1970).
