NEW YORK -- Before Eddie Van Halen agreed to add a guitar break to Michael Jackson's “Beat It,” one of the most famous cameos in rock history, he had to be sure the phone call from producer Quincy Jones wasn't a practical joke.“I went off on him. I went, ‘What do you want, you f-ing so-and-so!,’” Van Halen told CNN in 2012, 30 years after he worked on the song.
