He also says "Luke" a bunch of times in ESB, but not in ROTJ, which may be where they got the Luke line from.

Ever since reading the novelisation of the book, back in 1983, I've wondered how this scene played out. Great to finally see it. It would be a great addition to the film; I'd sooner see it re-inserted than as part of the bonus disc.
