Spot on GedKen! Paul McCartney's company has many a celebration of Buddy Holly and Paul (& Linda) always have (had) a fond word about Steve - there is a picture of Steve standing with Linda in a book about Abbey Road (EMI Studios).
Furthermore, Stuart played drums on one of Paul McCartney's hits No More Lonely Nights, turning up at AIR Studios complete with the Cockney Rebel logo on his drum cases!
