Hart was homosexual at a time when inevitably he had to remain deep in the closet. He was short in stature, an alcoholic, he suffered from depression and generally was full of self-loathing for his appearance.
Yet he wrote magnificent lyrics that would have won over many a romantic interest. It is thought that many of his lyrics were secretly gay love notes including the classic My Funny Valentine (1937) for which Richard Rodgers provided the music.
It remains a favourite 'torch song' of mine. Frank Sinatra's interpretation is as good as anyone's.
