Sister Kaite performance with Guest Sitting In at?????

Here we go this time I want to know 2 questions.

1. Who is the Guest Performer sitting in with Sister Kaite in this Pic??

2. Where is this performance of Sister Kaite taking place??

I remember this as being one of those gigs a musician just loves to play because this club owner was great to work for.

Now for the tip question...

3. Who owned the club at the time of this performance??
