I knew that over the years Dave and Henry Rollins became friends. (my impression I got when I saw interviews). Very good article on this website with Henry Rollins. He wrote a chapter about Dave in his latest book.
I guess what I can and cannot believe at the same time is what Henry Rollins said about Sammy Hagar.
"Speaking of getting the fuck out, Roth quit Van Halen and from the interviews, it wasn’t very clean split. To say that there were some hard feelings would be approaching it. In the meantime, the band hired on a new singer. Sammy Hagar, one of the most incredible turn-offs known to mankind—diabolical."
That is harsh. LOL
