Freddie also wrote Ogre Battle which is a very heavy metal guitar riff. It's strange that he should have done that. But when Freddie used to pick up a guitar he'd have a great frenetic energy. It was kind of like a very nervy animal playing the guitar. He was a very impatient person and was very impatient with his own technique. He didn't have a great technical ability on the guitar but had it in his head. And you could feel this stuff bursting to get out. His right hand would move incredibly fast. He wrote a lot of good stuff for the guitar. A lot of it was stuff which I would not have thought of, because it would be in weird keys. He had this penchant for playing in E flat and A flat and F. And these are not places that your hand naturally falls on when playing the guitar. So he forced me into finding ways of doing things which made unusual sounds. It was really good.
