Arlen's Goodbye Songs: " What's Good About Goodbye? "& " Don't Like Goodbyes "
" What's good about Goodbye"  is sung by Tony Martin who risks arrest by trying to leave the Casbah to follow Marta Toren. He sings the song knowing he may never see her again.
" Don't Like Goodbyes " is sung by Pearl Bailey in her role as a Madame Fleur in a Haitian bordello who knows some of her ladies will be leaving The House Of Flowers. 
Both songs express the sadness of departure and the unlikelihood of return.
