The Beatles at Shea Stadium was an event in 1965, a television special a year later, and is now a movie (or at least a second feature).     In this week's episode, the guys look at each of these iterations, compare and contrast them, and speculate on when (if?) we will see this project coming to home video.     After the cheers die down and the band is safely back in the Warwick, we jump forward 43 years to discover the logistics behind Paul joining Billy Joel for the "Last Play at Shea" on July 18, 2008, an event he describes as "coming full circle."
