I do this kind of thing all the time when no one’s watching — singing pop songs in someone else’s style. Personally, I prefer using the voice of non-singers like Indira Gandhi, but I understand Ms. Pedi’s choice of Liza and Carol Channing; otherwise, the P’town Gays she’s marketing to might not have gotten the jokes.
Also: is it just me, or does that Liza veer dangerously close to Shari Lewis territory? Come to think of it, THAT would be fucking hysterical. Somebody please crank out a Shari/Lambchop version of this video ASAP.
