Sammy Hagar said he regrets exposing Eddie Van Halen’s dark side in his 2011 autobiography.  “I apologize from the bottom of my heart for exposing his dark side.  And it’s true — it’s all true.  If I wrote the book today, I would only put the good of Eddie Van Halen, because he was such a brilliant, genius guitar player and such a great friend and a great partner — until everything went wrong. But thank God we got it back together.”
