In was 42 years ago Saturday (October 3rd, 1978) that Paul McCartney assembled Rockestra — the largest group of rock legends to record together up to that date. The cream of the rock elite joined Wings to record two tracks for their upcoming Back To The Egg album that day at London's Abbey Road Studios for the instrumental “Rockestra Theme” and “So Glad To See You Here.” Rockestra consisted of the Who's Pete Townshend and Kenney Jones, Pink Floyd's David Gilmour, Procol Harum's Gary Brooker, the Faces' Ronnie Lane, the Attractions' Bruce Thomas, and Led Zeppelin's John Paul Jones and John Bonham, among others.
Among those invited that couldn't make the session were Ringo Starr, Eric Clapton, Jeff Beck, and Jimmy Page — who never showed despite his amplifier making the session. Keith Moon had been asked to participate but had died less than a month before.
Despite “Rockestra Theme” being a guitar-based riff, Wings guitarist Laurence Juber recalled that McCartney often had guitarists shy away from their more obvious blues-inspired lead work while in Wings: “Where Paul wouldn't really go was into that kind of extended bluesy lead guitar solo. Now he'll go there more readily as part of the stage show; but then — I won't say that it was an area not to go, but it was an area to maybe hint at. Y'know, so I needed to be inventive. And he drove me to be inventive.”
