I rarely admit it, but because two people so kindly corrected me, I kind of have to let you all know that I am better informed now.
It wasn't Alaina that does the impressions. It is Kady Malloy. Here is her you tube from last night.
The good news, now I am not at all bummed that Alaina is gone...maybe we will get one more good impression from this girl before she goes. :)
