After spending the day on the Hill talking to members of Congress about protecting intellectual property, several Grammy Award-winning music producers headed to Carmine’s in Penn Quarter for an Italian feast. A Yeas & Nays spy spotted Adam Anders, “Glee’s” executive music producer (and music producer for the Tom Cruise/Alec Baldwin/Russell Brand movie “Rock of Ages”); Asleep at the Wheel frontman and Neville Brothers producer Ray Benson; Scott Hendricks, who has produced tracks for Blake Shelton, Keith Urban, Faith Hill and Alan Jackson; and Matt Serletic, producer for Aerosmith, Matchbox 20 and Santana. We’re told the creative clan ordered the spaghetti bolognese, country-style rigatoni, chicken parmigiana, Carmine’s salad, roasted peppers and mozzarella and manicotti.
