I was watching a movie called "Inside Llewyn Davis", and found this song somehow touching my heart deeply, maybe the tune, maybe the words, I don't know. I shared with Auntie Pearl last night; to my surprise, she hummed with it, telling me it was an old song probably 30 years back, that she loves it too. The film was a 2013 film so I took it a newer song obviously. Such a wonder that a song lasts that long and speaks to people from diferent generations and backgrounds.
Just like what said in the movie - it was never new, and it never gets old, then it is a folk song.
