GuitaristGreg Leon, who initially took Randy Rhoads's place inQuiet Riot, has claimed that he helped Rhoads write what would become the "Crazy Train" riff. "We were hanging out, and I showed him the riff toSteve Miller's 'Swingtown'. I said: 'Look what happens when you speed this riff up.' We messed around, and the next thing I know he took it to a whole other level and end up writing the 'Crazy Train' riff."[7] BassistBob Daisley has dismissed rumours that the riff not created solely by Rhoads.[6]
