While I hesitate to knock another musicians performance (she at least can play the...thing) I feel very sorry for her, ever enshrined as the crazy keytar lady who forgot to put on pants.
It might be my imagination, but does she mouth "Mom I'm sorry" at the beginning?
"Keytar" ... that's cool! Yeah, she's actually extremely adept with it! I'll have to check it again for the apology at the beginning. Ha! IMO she's got nothing to apologize about!
