This is a composite of two different audience sources: one is from Charlie Macasay's master audience recording while the other is from a 1998 Japanese bootleg from Absord Music Japan: [Bob Marley & The Wailers - Boston '76 - ABCP 8-9].
Both sources were remastered to remove minimal hiss & brickwalled sound.
