Happiest Gnome - Sidecar Inferno

So a friend of mine asked me if I could figure out the chords for Happiest Gnome for her. I guess it's a new song from that Gnome movie. I had a listen and to me it sounds like starting intro strumming G into the first verse which is G D C D Em. Anyone want to confirm my ear’s working right on that? The song is out on Yahoo music if you want to have a listen. Sounds pretty nice....coffee house acoustic type of song if you like that.
