While the taping wasn't live (it airs this Sunday), the producers tried to move the event like a live show, with all artists (besides Wonder) nailing their performance in one take. Was served as the musical director and also played bass for many of the artists that night.

But the moment that everyone � big-name performers included � was waiting for involved the two surviving Beatles, Paul McCartney and Ringo Starr, performing together. It's not that they haven't played together in recent years. In fact, they'd shared the stage at the GRAMMYs about 24 hours earlier, when Ringo sat in with Paul's band on Macca's most recent single, "Queenie Eye."

No real spoilers here � the show has been widely reported on, including our own review - but when Paul and his band finished "Sgt. Pepper's Lonely Hearts Club Band," they went right into "With A Little Help From My Friends" with Ringo joining them on vocals. That was the first time Paul and Ringo performed those two songs, back-to-back, as they were on the original Sgt. Peppers album. They followed it up with "Hey Jude," with Ringo behind the drum kit. "Ringo said this was the first time he played 'Hey Jude' since the Beatles recorded it," Was exclaimed.

When McCartney and Starr rehearsed for the Beatles tribute earlier in the day, the cast and crew on hand shared "a moment." "There were maybe 25 people in the audience, we got to the part where Ringo moved to the drums and they did 'Hey Jude,'" Was explained. "Those 25 people weren't sitting there to watch the rehearsal, they all had work to do. But at that point, everyone's jaws dropped. It was extremely powerful, and I know it translates through to the broadcast. And I know that people are gonna experience it when they watch it at home Sunday night. It was pretty incredible. I don't think you're going to see this again."
