Zero chance of this happening. When it comes to Metallica, Dave vasilates back and forth routinely between "I love those guys...they're my brothers" to "they are all liars, who cheated me and stole my songs". Bands are lined up around the block for an opening spot with Metallica, I doubt that they'll be interested in a jealous ex-girlfriend with borderline personality disorder and a well documented attitude problem. Dave has had a very solid career, he should stop demeaning himself by constantly talking about Metallica. Just my thoughts.
