In this song, Ozzy asks when we can all learn to love in a world gone mad. Ozzy wrote the song with guitarist Randy Rhoads and bass player Bob Daisley. In our interview with Daisley
, he explained how it came together:
"Randy had the basic riff, the signature riff. Then we worked on music together. He needed something to solo on so I came up with a chord pattern and the section for him to solo over.
Before it was called 'Crazy Train,' before we even had a title, Randy and I were working on the music. He had his effects pedals, and coming through his amp was a weird kind of chugging sound. It was a phase-y kind of psychedelic effect, this chugging sound that was coming through his amp from his effects pedal.
Randy was into trains - he used to collect model trains and so did I. I've always been a train buff and so was Randy. So I said, 'Randy, that sounds like a train. But it sounds nuts.' And I said, 'A crazy train.'
Well, that's when the title first was born. And then Ozzy was singing melodies and he was phrasing exactly how it ended up. And I started writing lyrics to it."
