I noticed that this song on the app has 7 chords. Is the 3 chord version coming back or was it ever there?
I’m not an app user so don’t have that context. I believe the original includes two key changes has JC moves through the verses. Perhaps that is what is going on in the app vs the simple version in Justin’s Beginner Song Book.
I forget what Justin may say in his Song Lesson. Perhaps give that a look see.
