"60 MINUTES" CAMERAS CAPTURE THE ASHLEE SIMPSON INCIDENT FROM BACKSTAGE AT "SATURDAY NIGHT LIVE" LAST WEEK FOR A REPORT THIS SUNDAY ON CBS

When Ashlee Simpson ran off the "Saturday Night Live" stage last week after her lip-sync flap, 60 MINUTES cameras were there to record her embarrassing exit and the reaction from show creator Lorne Michaels and other shocked staff members of the show. The exclusive behind-the-scenes footage of the incident will be part of a Lesley Stahl report about the making of the venerable comedy program to be broadcast on 60 MINUTES Sunday, Oct. 31 (7:00-8:00 PM, ET/PT) on the CBS Television Network.

Stahl and her cameras were also present for the dress rehearsal of Simpson's performance when she also ran off stage because her voice failed her, necessitating the now notorious live lip-sync performance that backfired.

60 MINUTES was at the show last Saturday night because Stahl had been shooting footage and interviews all week for a report on how the show is put together. Viewers this Sunday will learn and see how the show is conceived, written and produced each week.
