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 "Linda McCartney Dies Of Cancer").

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.
