Loves Old Sweet Song was very popular for a very long time:
- written in 1884
- published in the 1890's as sung by Antoinette Sterling
- sung by a character in Ulysses (1918-20)
- sung by a drunk in Sean O'Casey's short play Pound on Demand (1932)
- played or sung in at least 14 movies (1923 to 1997) according to imdb.com
- the name of the song was used as the title of 2 feature films and 3 shorts (1913 to 1933)
I learned it 30 years ago when I played the part of the drunk in Pound on Demand. I still sing it today, more in key I hope, and with classical guitar accompaniment.

My parents' special song was You Are My Sunshine. My father used to sing it, kind of like this (Gene Autry?), but a capella, and slower, lower-pitched, and more plaintively.
