At the National Orange Show Events Center in 2006, the event I could verify was British Invasion 2K6 , which featured GBH and The Adicts ; one report also says Vice Squad was part of the lineup.

What was playing

  • The Adicts.
  • GBH.
  • Vice Squad.

Context

The reports I found tie this to a punk concert that turned chaotic after a stabbing was reported, with the show identified as British Invasion 2K6 at the National Orange Show Events Center in San Bernardino.

If you meant a different National Orange Show event in 2006, the exact lineup would depend on the specific date or festival day.
