I have always stated Lindsey's firing is almost as silly as the Sammy Hagar and Michael Anthony firings. No clear reasons except someone who controls that band has a beef with someone. I heard this on Stern the other day and glad this clip was posted. Sammy has no idea why he was fired from Van Halen except he made Eddie feel "insecure." Sammy states he recently tried to make amends and called Irving Azoff to dinner with Eddie but they would not even respond.
