I suggest people read the article. Basically, Sammy is saying EVH is beyond a drunk crazy person.
Sammy's comments about Michael center around how the VH brothers regulated MA to a sideman position on the 2004 tour and really lowered his income as opposed to the four way split it always was. I get the impression Sammy thought it was uncalled for, mean spirited and down right low.
I was impressed in the article how well it seems Sammy has his head screwed on.
One exmaple he gave was at the end of the tour, he had bottles of his tequila his company produces. He had a bottle for each of the 127 employees on the tour he was autographing and was planning on giving to each employee. Apparently, while signing bottles, EVH came and started to grab a bottle to drink. Sammy explained to EVH that he has an exact amount and not to touch them because that meant an employee would be left out. EVH didn't care and basically made comments it's all about him, etc. Very sad really.
Sammy also talks about the lack of personal hygiene, EVH pulling his own teeth, missing many teeth and the remaining being black anyway. really, really sad.
