When Han is frozen in carbonite in ESB, Lando tells Vader he has died. Vader then tells Fett he’ll compensate him if he’ll remove the body. Later when Lando tells them about the east platform, he says there’s still a chance to save “Han’s body.”

In the crawl for ROTJ, we learn that Han’s goofy identical twin has joined up with the rebels. We also learn that he is temporarily blinded due to a medical condition that flairs up now and again. They still try to infiltrate Jabba’s palace to retrieve the body, Han’s brother with them. But he ends up being more of a hindrance than anything. The group get caught and sent to be executed without having gotten Han’s body. Oh, well.
