This was a great concert, part of which ended up on Frank's steller release CHUNGA'S REVENGE

I remember that the concert program was printed on bubble wrap and by show time the hall was loud with patrons poping them.
The band walked on stage with half off a female maniquin and Frank settled in front of his mic and said "Don't kid yourselves, you are all wearing uniforms."
They did several tunes including an extended version of King Kong.
The 1970 band just 2 months after I saw them
