Introduced by Cliff Michelmore
with Derek Hart, Alan Whicker, Fyfe Robertson, Trevor Philpott, Kenneth Allsop, Macdonald Hastings, Christopher Brasher, Julian Pettifer, Brian Redhead.

At precisely seven o'clock this evening that bouncy little tune that goes 'rum-tum-tum-tiddley, tiddley-um-te-tum' will be sounding out for the 1,596th time to introduce another edition of Tonight. And by the time Cliff Michelmore says 'Goodnight and the next Tonight will be tomorrow night' the total number of people interviewed on the show will have risen to 6,387 - roughly the population of Bodmin, Cornwall. Not that they all come from Bodmin, of course; for example, the gentleman who made his own set of false teeth out of concrete certainly didn't.
According to one unofficial estimate, Fyfe Robertson will have posed the question 'but do ye rreally like doing this?,' for the 472nd time, and Cliff will have been interrupted by the telephone for the 1,647th time.
The total amount of film which the programme will have exposed will add up to just under 563 miles. If made up into one reel this would be enough to form the base for a rather small gasometer, while if it were laid out in a single continuous strip it would stretch from Lime Grove Studios in London to a point just short of Stavanger, Norway.
Besides the strange and wonderful assortment of people who have appeared on Tonight, the programme has also featured a variety of animals. These have included the tankful of tropical fish once used as part of the set (all but one of which perished on duty in a studio accident), elephants, horses, various breeds of monkey, birds talkative and otherwise, dogs, cats, and kangaroos. It has been calculated that if all these non-human Tonight guests were assembled in one place they would stock a somewhat curious zoo approximately one-third the size of Whipsnade.
