Juan Diego Flórez, who — if this costume design is to be believed– is planning to play Almaviva as a gay pirate, will headline a mini-company from the Met appearing on “Late Night with David Letterman” tomorrow night, November 8, 2006, at 11:35 p.m., ET, on CBS. The boyish Rossini tenor and his colleagues Diana Damrau, Peter Mattei, John Del Carlo, and Samuel Ramey will perform a fully-staged version of the Act 1 finale from the Met’s new production of Il barbiere di Siviglia, conducted by Maurizio Benini and directed by Bartlett Sher. (Dave’s other guests include Dustin Hoffman and “Naked Chef” Jamie Oliver — oh, yes, it’s sweeps month, all right!) Of course, Wednesday is a school night, La Cieca will set the DVR, and she is sure the scene will be available for next-day viewing on the streaming video page of cbs.com.

In response to your demands, cher public, La Cieca has scheduled another of her wildly popular live chats for the evening of Friday, November 10. You are invited to join in what will no doubt be a most spirited discussion of the Sirius/RealNetworks broadcast of the opening night of the Barber. The room will open at 7:45 for the 8:00 start of the performance.
