How to play "Purple Rain" on the guitar.

I found this on youtube. This song has been played and taught in different ways, but this one sounds pretty close to the original.
I've always loved the guitar in this song. That last chord (E flat add9) is sweet, but I it's a little hard to play.

It was interesting that Prince had to call Journey's keyboardist to make sure that they wouldn't think he was stealing from them. Apparently, the song "Faithfully" uses the same chord structure.

Anyway, I thought all of you guitar players out there would like this.
