"September Song" is an American standard composed by Kurt Weill, with lyrics by Maxwell Anderson.
It was introduced in the 1938 Broadway musical Knickerbocker Holiday, and has since been recorded by numerous singers and instrumentalists. It was used as the credits music for the BBC sitcom "May to December."
Here is Jimmy Durante doing a surprisingly (I had no idea he was this musically talented) good version on "The Colgate Comedy Hour" in 1955:
James Brown recorded the song in 1970 on the recently re-released album Soul on Top. This release was a collaboration with big-band jazz drummer Louie Bellson. Lindsey Buckingham also recorded a slightly odd version of the song on his debut album Law and Order, but that's what years of touring with Fleetwood Mac during the 1970s will do to a person. Liverpudlian Ian McCulloch, lead singer of Echo and the Bunnymen, released a version of the song as a solo single in 1985. It sort of makes sense he'd do a version. Here is the video for it:

And here is the version done some twenty years later for the September of My Years album in 1965, when he was old enough to truly understand the song's meaning:
Finally, for sh*ts and giggles, here he is doing a duet with, heh, John Denver. This is undeniable proof of Sinatra's acting ability. He actually looks like he's enjoying this (from the 1977 TV special "Sinatra and Friends"):
