Audience response back in the day?

[louielouie2000]

So everytime I watch the Tusk Documentary I wonder if they edited in the audience cheers in for the live performances. On Sisters of the Moon especially, the audience goes totally apesh!t anytime Stevie even raises her voice lol. Were those audience shots and cheers edited in, or did the band really elicit that kind of response from crowds in the late '70s?
