Sambora tells The Sun he definitely won't be on stage when the band appear at Hyde Park on July 12. "I truly want to be there, and I feel very sad for the fans that I won't be performing," he reports.

"It's just not happening right now. Jon and I have been tight for, like, 30 years. All this is very sad and it affects so many people around us."

Sambora calls the situation "a family drama" and insists "it will be resolved."
