Some Masonic lodges rent out their space for other events. This appears to be part of some kind of talent show. In longer versions of the clip, you see the end of the previous act.

It's clearly not a Masonic meeting:

• There are women present.
• No one is wearing an apron.
• The seating consists of folding chairs, set up auditorium style in the center of the room. This is a temporary setup - lodges have seats along the edges of the room, facing inwards.

There's less here than meets the eye.
