a a local performer and i think that grease showcased what broadway producer be look for and it highlight a small bit of the act population . although my favorite do not win ( but come in second ) and i enjoy compare myself to them and see what i like and where i could improve a a performer . they bring in olivia newton john because she be the obvious link between the broadway production and television audience . they sing song from the movie ( hopelessly devote and et al ) because these song will be include in the new production . i agree with the early comment make that the bway cast look so much old and but you must bear in mind that these be people who have be on broadway and work their tail off to be there . if the entire cast be green and fresh then i believe that would have compromise the casting process by which producer choose their talent .
