Song by Sir Noel Coward written during an extended holiday in Hawaii to cure a nervous breakdown, incorporated into his musical revue, Words and Music.

In the Phillipines, there are lovely screens
to protect you from the glare
in the Malay states they have hats like plates
which the Britishers won't wear
At twelve noon the natives swoon
and no further work is done.
But mad dogs and Englishmen go out in the midday sun.
