Songbird Susan Boyle is set to make her acting debut, in the second season of Glee, according toRyan Murphy. Murphy, a creator of the Fox musical comedy series, said at the Television Critics Association press tour on Monday that she’ll appear in a Christmas episode as a high school lunch lady (that’s kind of dead-on casting). Also, Murphy says Paul McCartney has offered the show his music. “It came out of blue in a package, handwritten, and it had two CDs and it said ‘Hi Ryan, I hope you will consider some of these songs for ‘Glee’ … I had heard that he is a fan of the show. I was gob-smacked … so of course we are going to do something with him,” Murphy said.
