Nice catch. He mentioned it is hard for him to tell he was developing a voice (style) as opposed to just a mix of influences. It took somebody else to tell him (Fates Warning's Frank Aresti).
Yeah, that was really cool. When I saw them the last time on the last tour, I got to get in for sound check, and Frank and his wife were there on the side of the stage by JP. After sound check, I was just hanging out in the auditorium, and the rest of the band had gone backstage to get ready, but JP stayed out and was talking with Frank, and you could tell that they have a really close friendship. It was cool watching/listening to them interact. (It was also cool getting to meet Frank myself, although I felt like a bit of a doofus with not much to say, since I have not really followed Fates that closely, especially in recent years, and couldn't even remember for sure at the time whether Frank had played on the most recent album)
Another funny/cool moment from the video was when John was talking about G3 and how he had drawn so much influence in his own playing from Satch, Vai, and Morse that when he was soloing with them initially, there was almost a moment of panic where he was mentally running through some of his go-to solo licks and having to scratch them from the list because they were taken right from those guys. I liked the, "oh, Yngwie's not here; I can use that one!"
