Milano, this topic is for discussion of your mother and you are certainly most welcome here. However, you are not welcome to come on personally attacking someone who is voicing their opinion of one action of your mother's that he did not approve of.
As a DJ traveling though Europe with Susanne, I daresay Johnny Dynell was not envious of her or anyone else on that bill. We were both shocked and disappointed in her show that night - I was also there. It is NOT okay to throw handfuls of liquids or anything slippery into club audiences - besides ruining someone's night, it is dangerous from a slip and fall standpoint.
I understand that those lines must have been very blurry because of the norms of her act, which she was booked for. But like the piercing show performers who began to throw dirty piercing stakes into the audience at another show, sometime the "fourth wall" must be a bit more unbreachable.
