"Glenn Hughes, who has never previously spoken in detail of his deep, but troubled friendship with Bowie, believes that David had sent himself on a journey deep into the cocaine mindset in order to create new territory for his art. Bowie had never really suffered for his music before; not like Iggy, or Vince Taylor – mocked and vilified by the masses.

It twisted and turned him inside out.’"
