The Tin Man expresses in "What Would I Do If I Could Feel" just how badly he misses his humanity, and how strongly he hopes having a heart will bring him closer to regaining it.
The 1984 revival adds a particularly heartbreaking moment to 'Home'. As Dorothy hugs her friends goodbye and moves to centre-stage to continue singing, the world of Oz slowly fades into darkness around her. The last image we see of Scarecrow, Tinman, and Lion is the three of them huddled in shadows, reaching forlornly for Dorothy as if trying to call her back one last time.
The TV special
A Kalidah exploits Dorothy's grief for losing her parents, by disguising as Dorothy's mama. Dorothy, surprised to see her mama again, doesn't ask how she ended up in Oz, and when the Kalidah claims that she needs the Silver Shoes in order to reach Dorothy again, Dorothy becomes more than willing to give them up...until the Tin Man alerts her of the Kalidah's trick.
The Scarecrow, the Tin Man, and the Cowardly Lion sadly walking offstage after Dorothy bids them farewell, then starts singing "Home" to return to her Aunt Em's farm.
