Dave Mustaine recently spoke to the World Entertainment News Network (WENN) about the return of David Ellefson. "He's the best bass player for Megadeth and he's been there since the beginning," Mustaine said. "The time without him was difficult for me. He was my partner and one of my best friends. I asked him to forgive me, too, and that's really important too because I realized that I had made a lot of mistakes in my leadership. I was a kid when we met and, granted, I was an adult when we parted ways, but I made a lot of mistakes along the way that affected him. We're still working through all this stuff and talking about the future."
