I've just watched "The Supersizers Go Seventies", available to UK viewers here -
iPlayer link - for another three days. At the end the MIB said "You enjoyed that rather too much ;-)" - he did too.
Recommended if you like any or all of purple suits, prawn cocktails, Blue Curacao cocktails, epic cocking about, food porn, dodgy nostalgia and history, Concorde, Smash, cheese fondue followed by chocolate fondue, D I S C O etc etc - and the music was brilliant too.
