One of the most famous songs with a month in the title is September Song by Kurt Weill with lyrics by Maxwell Anderson. A beautiful song, written in 1938, and recorded many times. I love Lotte Lenya's version from 1957. Lenya was married to Weill (twice!).
Weill is perhaps most well known for the Threepenny Opera, which Bertolt Brecht wrote the libretto for. Lotte Lenya recorded it, or parts of it, in the 1930s as well as later. There are numerous versions by her and others of songs from the opera. There are plenty on youtube, for example.
Autumn is here.
