Riding a motorbike in the center of a motorcade around London, she made a bid to appear in the most musicals ever in one night. And, she did set the record, putting in cameos in no less than six shows.

At 7:40 PM she was on stage at Her Majesty’s Theatre with the cast of Andrew Lloyd Webber’s The Phantom of the Opera. By 8:04 she was down the road cavorting as a prostitute at the Palace in Les Misérables; 8:35 saw her at the Aldwych in Fame, before popping in to the Phoenix for Blood Brothers.

With the night wearing on and time running out, she high-kicked with the cast of Anything Goes at the Theatre Royal, Drury Lane, at 9:25 PM. And 45 minutes later, Chitty Chitty Bang Bang brought the total to the record-breaking six musicals.

This bravura turn was to mark the London mayor’s One Amazing Week — seven days designed to promote the capital as a tourist destination. Hall takes her place in the Guinness Book of World Records, having entertained 9,214 theatregoers in the one night.

Hall has previously appeared in the West End in The Graduate, playing Mrs. Robinson, for which she famously stripped.
