That line is present in the 1977 mono mix, and the two Special Edition mixes (1997 and 2004).
I see. The mono mix came after the 70mm soundtrack I think. I guess the 06 DVD of Star Wars is closer to it's original form than I thought since the it doesn't contain the "close the blast door" line, Luke's alternate "blast it wedge" line, or CP30's tractor beam explanation. None of which I heard in the recording.
