How to play Five Years Time by Noah and the Whale

First off, many thanks to youtuber marcthaine for introducing me to this song a few weeks ago. It's a fun, simple, cute song, and a good video too.

Check out the original song here: Five Years Time by Noah and the Whale.
And the chords and lyrics from ukulelehunt.com here.

And my tutorial video here:

Video breakdown:
0:00 - Intro
0:08 - Tuning (GCEA)
0:14 - Chords (C, F, and G)
1:42 - Chorder
2:05 - Strumming pattern (down - up - hit - up, switch and repeat)
2:53 - Tricky part in strumming (hiccup on the C only)
3:33 - Demonstration (starts slow, speeds up)

The song itself has only three chords: C, F, and G. The video goes over two possible options for which G to play. I think it's easier to play the standard G, but if you bar the second fret and put your fingers in the F position, you'll get the exact G he plays in the video, which might be worth it if you can do it well.

The chorder just repeats: C, F, G, F over and ver and voeover and over and voer anbdnvoer.....etc

The strumming pattern is
1) down
2) up
3) hit
4) up
(switch chords and repeat)
