To some viewers 'Wingspan' documentary may be a little disappointment. There is and was still a lot of topics the documentary could have contained too but as you can in general make only a limited lenght programme the creators chose to concentrate mostly on Linda McCartney. The main author of the programme is Paul's oldest daughter Mary who carries out the interview with Macca. There will also be a lot of archive material with some short excerpts from Wings' performances. If you want to hear Wings music in lenght you should buy some Wings records, even some others than the Wingspan CD collection.
Despite the fact that Paul is the only ex-Wings member that is interviewed for this programme, it still is an valuable insight into a band that will forever be over-shadowed by the Beatles (and even Plastic Ono Band). Linda is not here anymore to give interviews and only Paul and his family members can present us with some new details about Linda and her career in the Wings.
Hopefully this documentary will not be the last effort to make Wings a little more appreciated post-Beatle band. The value of the information what the other band members like Laine, Seiwell etc could give would make another and possibly a more interesting documentary film. Even without other the Wings' members 'Wingspan' still manages to present some honest new information from Paul, so it's still a very valuable item.
