Surviving Beatles Paul McCartney, George Harrison and Ringo Starr will perform together today at a memorial service for Linda McCartney.

McCartney died of breast cancer in April (see [article id="1425543"]"Linda McCartney Dies Of Cancer"[/article]).

UPI reports that the three will perform "Let It Be" with 700 invited guests at St. Martin-in-the-Fields church in London. It will be the first time the three have performed together since 1969.
