On the back of Morgan Neville's new "Man on the Run" documentary, Ned and Paul reassess the importance of Linda McCartney in Paul's life from the breakup of the Beatles until her passing in 1998. Critical barbs about her musicianship and taking "the old lady" on the road (or, OK, even "Cook of the House") notwithstanding, the evidence shows that the wealth of nuggets from Paul McCartney's catalogue over that 28-year period very likely would not have existed without Linda's presence.
