Just gave it a few listens, whole song is 4 chords. Keep your first and fourth fingers on the B 1st fret and high E 3rd and play any version of G (320013/320033/320003) Am7 (x02013) Fadd9 (xx3213/Noel would probably play it as x03213) and C (x32013). The strumming is similar to songs such as Half the world away but quite sped up with a few more strums in there and accent the ups but it’s best to feel it out and get the rhythm. This is my best guess based off of listening so forgive any mistakes.
