Care to join me in a tribute to Linda McCartney?

Question

Watch this clip and the answers will come in the same order as the questions.
1. Linda is sitting on the ground holding Paul's leg. What part of Scotland are they in? ( a die-hard fan will know.)
2. Linda is holding her hands in the "Wings" symbol. Who is at the far left in this picture?
3. Linda and ?????? are sitting in a field of red flowers.
4. Paul and Linda are sitting on a log, over a stream. What album was being shot in which a similar photo was the cover?
EXTRA CREDIT QUESTION:
A smiling young child is holding sheet music ? Who is the child and what's the story behind the song? You can see the title of the song if you pause the film. A TRUE Linda devotee will know this.
REALLY!
