ALW constantly used melodies from shows that didn't do well or didn't get off the ground in his later musicals. For example, in Sunset Boulevard during the middle of " As if we never said Goodbye,"
"I don't want to be alone, that's all in the past. This world's waited long enough; I've come home at last."
Exactly the same tune, key and everything, as the middle eight in "Half a Moment" from By Jeeves.
" Constant spinning memories, spin before my view, like a toy kaliedoscope, images of you."
Keep your morals, I don't have time. Keep your lovers, I'm changing mine!
