If you want to see what real rock n' roll looks like and a band enjoying their music then watch this clip from The Who's 1979 rockumentary The Kids Are Alright. Basically, the band didn't feel they had captured solid recorded versions of some of their hit songs, so at their own Shepperton Studios they filmed live recordings in front of a small audience. Now when I say "audience" it was an audience made of close friends, special invitation and fellow musicians to the tune of 500 guests. I believe...at a minimum the adult beverages had been free flowing and what originally started as a recording of a few songs became a full out concert due to the re-takes.
