This song is Un-mistakably associated with Al Jolson. It was written by two Jewish brothers -- George and Ira Gershwin. One wrote the lyrics (words), the other wrote the music. Al Jolson (the World's Greatest Entertainer) introduced it for them. That catapulted the Gershwins to stardom. A lofty position of respect and public acclaim. From which they were able to write many other outstanding popular show tunes.
Thanks for your kind comment! I transcribed the disc improvisations (a bunch of them are on this channel), but I did not transcribe the piano rolls. This transcription of Swanee was done by Artis Wodehouse. This folio, titled "Gershwin plays Gershwin", can be purchased used on Amazon and eBay. If you're interested in the disc improvisations, I can send those to you.
