Al Gore was in the audience on Feb. 11, 1964, when the Beatles played their first U.S. concert on a makeshift stage -- a boxing ring, actually -- at the Washington Coliseum, not far from Union Station.

Where were you when you forged your first Beatles memories? In front of your TV set, watching the Beatles take the Ed Sullivan Show by storm? Glued to your radio the next month, squealing over "Can't Buy Me Love?" Or did you see Paul McCartney at RFK Stadium in 1990, when after a seemingly interminable hiatus, he gave the audience exactly what they had hoped for, delivering more than a dozen Beatles tunes?

On Friday, McCartney returns to Washington with "Out There," a magical mystery tour that has synthesized the decades -- the shaggy mod years, the Indian sojourns, the rocking Wings era -- into three pat, nostalgia-fueled hours, much of it dedicated to the Beatles' remarkably vast catalogue.
