<P> Berkeley Square (pronounced "Bar - klee") is a large leafy square in Mayfair, an expensive part of London . The Ritz Hotel referred to is also in Mayfair . </P> <P> The nightingale, a rare native songbird, is celebrated in literature and music for the beauty of its song . It favours rural habitats, and is unlikely to be heard in Central London . </P> <P> The song was written in the then small French fishing village of Le Lavandou--now a favourite resort for British holidaymakers and second - home owners--shortly before the outbreak of the Second World War . According to Maschwitz, the title was "stolen" from a story by Michael Arlen . The song had its first performance in the summer of 1939 in a local bar, where the melody was played on piano by Manning Sherwin with the help of the resident saxophonist . Maschwitz sang the words while holding a glass of wine, but nobody seemed impressed . In the spring of 2002, an attempt was made to find the bar where this song was first performed: it was hoped that a blue plaque could be set up . With the help of the local tourist office, elderly residents were questioned, but it proved impossible to identify the venue . </P> <P> The verse and the additional lyrics to a second chorus were in the song as written, but are rarely sung in recordings (those of Bobby Darin, Mel Torme, Blossom Dearie, Twiggy, Vera Lynn and Rod Stewart being notable exceptions). Twiggy's version was featured in an episode ("Fran's Gotta Have It") of The Nanny . </P>
