[3] It contains live performances by Wings, the Who, Queen, Elvis Costello, Pretenders, the Clash, the Specials and other artists from the Concerts for the People of Kampuchea, held at London's Hammersmith Odeon in December 1979 to raise money for the victims of war-torn Cambodia.

The name was first given to an assemblage of famous rock stars that were brought together by McCartney for the final Wings album, 1979's Back to the Egg.

The supergroup – which consisted of Wings, John Paul Jones and John Bonham of Led Zeppelin, David Gilmour from Pink Floyd, Ronnie Lane of the Faces, Kenney Jones and Pete Townshend of the Who, and Hank Marvin of the Shadows – recorded two McCartney compositions, the instrumental "Rockestra Theme" and "So Glad to See You Here".

Then, McCartney and Kurt Waldheim re-assembled Rockestra for a series of benefit concerts for the people of Cambodia (also known as Kampuchea), suffering from the reign of Pol Pot.

This time, Rockestra consisted of, among others, Wings, John Paul Jones, Bonham, Robert Plant, Rockpile, James Honeyman-Scott and Townshend.
