Osbourne's second album, "Diary of a Madman", featured more songs co-written with Lee Kerslake. For his work on this album and "Blizzard of Ozz", Rhoads was ranked the 85th-greatest guitarist of all time by "Rolling Stone" magazine in 2003. This album is known for the singles "Over the Mountain" and "Flying High Again" and, as Osbourne explains in his autobiography, is his personal favourite. Tommy Aldridge and Rudy Sarzo soon replaced Kerslake and Daisley. Aldridge had been Osbourne's original choice for drummer, but a commitment to Gary Moore had made him unavailable. Sarzo had played in Quiet Riot with Rhoads, who recommended him for the position.
