Looks pretty legit to me. They may be unreliable in some things but I'm pretty certain some doucher wouldn't make this setlist up for shits and giggles.
I don't know how reliable it is, but my friend's dad is Mark from Great White and I heard from him that Slayer used to be a hair metal band right when they started. They were completely glammed out and one day just changed their image and sound and became the Slayer we know and love.
