1960s England - Chelmsford is a boom town with Marconi, a milk bar, and mods and rockers. As Alan Price croons 'I'll Put a Spell on You' and Tommy Tucker puts on his 'Hi-Heel Sneakers' the Vespas pull up outside the Orpheus coffee bar. Things happen - a rock'n'roll star comes to tea, Bill meets Marie's parents, Deirdre bakes a birthday cake for Chelmsford's hero, Mick, who was blinded in a crash with a rocker, and Sandra and Linda leave for a wild walking holiday on the Isle of Wight. A wedding, a ban the bomb march, a cocktail party and a stolen gift, all create A Sense of Occasion. Award winning author Elizabeth Woodcraft's interlinked stories describe life growing up on a working class estate in Essex, and show how the Sixties made four Mod girls into the people they became.
