Hughes and three other crewmen were originally suspected of murder and spent a night in jail, before authorities released them. The following night, Purple abandoned their second of two Jakarta shows after heavy-handed police officers began assaulting members of the audience.

Hughes recalled last year: "That sh*t was flying - we were in a time bomb in the midst of war that had just started in the country. All of us were lucky to escape alive."
