I had three VH albums in my top 10 favourite albums when I voted on that other thread as I did Zep (my two favourite bands).
First time I saw VH was supporting Black Sabbath. I saw them eight times with Roth; four times on their 1980 invasion tour and then their first Madison Square Garden gig the following year, which was something else - helluva way to start one's first trip to America. Loudest audience I ever heard and Roth had them eating out of his hand, perhaps the best performance I ever saw by a frontman.
Eddie quite possibly is the best guitarist of the lot.
I was a Hagar fan before he joined VH and I don't mind Van Hagar but Roth was as important to VH as Eddie.
