Specifically those with Biggs. When I saw the movie in theaters in 1977 I know I saw at least pieces of these in the movie. I know I saw Luke looking at the battle, I know I saw Biggs walking away from Luke at Toschi Station.
You appear to be suffering from false memories. Steve Sansweet (ex-Director of Content Management and head of Fan Relations at Lucasfilm) has said that the movie was never officially released with these scenes.
