Does any one know who sings a specific version of Last Christmas? - who does myamme hair

I work at Urban Outfitters, and sometimes play this version of the song last Christmas. He is a singer and was a flat and a little hoarse. It is acoustic. If you have any idea who he is, please let me know. Thank you.
