The live proficiency of Australian 'pub-rock' bands of this period is widely attributed to their experiences playing in the rough-and-ready atmosphere of the pub circuit. Unlike the frenzied but generally upbeat atmosphere typical of Sixties pop shows, pub gigs could be a testing experience for even the most accomplished band. Often as not, a significant proportion of the audience were in varying states of intoxication, and groups who did not provide the kind of performance that was required by the audience would be mercilessly heckled by dissatisfied crowds.
