It is just possible that I heard "All by Yourself in the Moonlight" on the radio as a child in the 1940's but I had certainly completely forgotten this music-hall song until I rediscovered it while browsing through 101 Pub Favourites for Buskers
This is a fine piece of nonsense from the 1920's written by Jay Wallis (words & music) on the inanities of being alone in the moonlight, regardless of gender. The title, "ALL BY YOURSELF IN THE MOONLIGHT" is roared out spoken in the chorus which makes a nice change for an audience. The phrase "Love's a farce, sitting on the grass"
simply demands amendment by this vulgar senile old sod and is indeed often done when in my cups.
