of the announcement that the girl had just had a throat infection.
I think that caused most to feel she wouldn't be able to get through the song at all, and in fact she did. Wasn't all THAT, but she did sing well.
I actually enjoyed that they were able to include a few mini-solos by the guitar and drums, so it wasn't all about her.
But, in reality, there is no way they are ready for a show of their own, or even a record. IMHO, anyway...
