During part one of the two part special with King, he discussed his involvement with Megadeth during their early days and while he heaped praise on Megadeth founder Dave Mustaine's talent, he also explained that he "had Slayer's best intentions in mind" while playing with Megadeth.

King told Loudwire (as transcribed by Blabbermouth), "I was one of the lucky people - and there's certainly no offense against [current Metallica guitarist] Kirk Hammett; Kirk's a wonderful friend of mine - but I was lucky enough to see Metallica with [Megadeth mainman Dave] Mustaine. And I say that because it's just a rare thing to be able to say that. I saw them play with Woodstock [in Los Angeles], and I was so intringued by Mustaine, because he was just ripping on guitar and looking out that way somewhere. And I can't do that to this f***in day.

"So I was just blown away at his guitar playing. And to find out - I think it was through B.C. Rich, 'cause we all played B.C. Rich back then� I think it was through B.C. Rich I found out that Dave was inquiring if I would play [with Megadeth]."

He then explained his motivation for taking the gig, "At the end of the day, I thought, 'This is a gigantic learning situation.' And I also thought people would see me and know me from Slayer. 'Cause, I mean, we only went to the Bay Area; we only got up there. So I think if people saw me, it would at least make 'em think, 'Slayer.' So I had Slayer's best intentions in mind. I didn't go and say, 'Hey, I wanna be in Megadeth.' I don't know how anybody can be in Megadeth for more than a couple of hours, 'cause that guy's crazy."
