The Big One: Alan Gilbert Conducts the 'Sanford and Son' Theme For '30 Rock' Even if -- especially if? -- you are Alan Gilbert, you don't get to appear on a show like "30 Rock" without getting pulled down to its silly, satirical level. On Thursday night's episode of that NBC comedy, Mr. Gilbert, the music director of the New York Philharmonic, found himself an unknowing pawn in a battle between the characters played by Tracy Morgan and Alec Baldwin (who in real life is an enthusiastic patron of the Philharmonic and a member of its board). That feud culminates in the above scene, which finds Mr. Gilbert conducting an orchestral arrangement of Quincy Jones's "The Streetbeater" -- better known to us big dummies as the theme to "Sanford and Son." We'd like to think Redd Foxx would approve.
