A guest meets a pair of closed velvet curtains with a top hat on them. Tapping it lifts the hat, the curtains sweep apart, and the bill is revealed — the child's name, their age in a fat-face numeral, and a living flip-photo cycling through a burst of stills at the foot of the page. From there the show runs one screen at a time: the date under a live countdown, a hand of playing cards a guest taps to learn about the birthday child, the running order of the day, the acts on offer, a fanned hand of memory-lane photographs, a six-question guessing game with a score at the end, a drawn map to the venue, the house rules, and a reply form.
