After Surbiton bank clerk (third class) Anthony Marigold-Bentley marries Edith, they honeymoon in South America. Before you can say "King and Empire" they are up the Amazon without a paddle or a teashop in sight as they go in search of the legendary see-through frogs described by missing explorer Bertrand O'Flannel in his diaries.
Soon the couple have run out of small talk and milk, and they are not sure the natives are friendly. But it is 1922 and they have British passports so they don't worry too much - and break into song at every opportunity. But why is that man with a grand piano following them?
Written by Right Size regular Chris Larner, this is non-stop silliness that sends up the British abroad and theatrical conventions with a highly developed sense of the ridiculous, wit and four cracking performances. It is a very little show of a very particular kind hailing from somewhere close to the Loose Ends region of Radio 4. But it does what it does with enormous charm and gusto, and a slickness that many Fringe shows lack. Real old-fashioned fun.
