Meet and greet hypnotist!

I have just performed at a wedding reception!
Nothing unusual in that, in fact they usually go really well and I like doing them.
The problem - I originally thought I was going to have about 70 guests, on arrival I find out that there are only about 35 guests and about 4 of them are children, plus the bride and groom have decided to keep my performance a surprise.
The venue is not ideal either, on entering the building you come into a foyer, off to the right is the room they are holding the wedding breakfast in, next to it is a doorway to the bar and toilets, on the other side is a small room and another doorway to the kitchens etc.
The hotel manager originally suggested I set up in the small room until I pointed out there would be no where for the guests to view the show from, then we decided to move the show to the foyer, I set up my PA etc and sound checked then to find a mobile disco arriving and wanting to use the same area as me!
On discussion with the DJ we decide to loose my equipment and I plug in through his system.
This then led to a very unusual result, In my 'optimism!' I have decided to set up with 4 chairs, despite there only being about 30 adults, it being a surprise cabaret, there being no seating for my audience and the limiting conditions I manage to get 12 volunteers and work 9 of them. It was a really good show and everyone, young and old, thoroughly enjoyed themselves!
