In a deleted scene from EMPIRE, set just before the Vader dinner scene, Lando takes Han, Leia and Chewbacca on an outdoor walkway tour of the Bespin mining colony. Why the scene never made the final cut is unknown-perhaps lack of time and advancing release date pressures at ILM saw it cancelled.
Scene dialogue as from the Marvel Comics adaptation 1980:
Leia: It's a lovely outpost, Lando.
Lando: We're proud of it. The air is quite special here...stimulating. (To Leia) You could grow to like it.
Han: Only until the Falcon's repaired, old buddy.
