The question asked was whether Liza is OVER-rated, in a particularly nasty way, by suggesting that she is where she is only where she is because of her parents.

To which the answer is a resounding NO.

I can't imagine what that Salsa Celtica clip is supposed to show (other than everyone is having as good a time as is possible to have at Cambridge (i.e. not very).

Far more to be recommended is seeing her with the Ratcatchers, with Martin Green or Chango Spasiuk.
