CORRECTION: Typo in the May songwriting challenge

Thanks to my good friend John Raymond Pollard for bringing the typo to my attention: In the May songwriting challenge, the chord progression is correct the first time it appears, i.e. I--V--vi--IV

In my detailed explanation, I reversed the vi and the IV

So, just to be clear:

Major ONE chord, Major FIVE chord, Minor SIX chord, Major FOUR chord, back to Major ONE.

I apologize for the error.
