RIP sir, those first 2 Maiden albums were perfection.
Dennis Stratton was out before Di'Anno, though (Adrian Smith played on Killers).The one thing I have always liked about the guy is that he put his hand up and said he was partying 24/7 while Steve Harris wanted to focus on the music and not the lifestyle so much(this also lead to Clive Burr's and Dennis Stratton's ouster from the band later.
