onhighway61, although they are not mentioned by name, you should know that Dylan's "Ballad in Plain D" was about Suze Rotolo and her sister Carla. From Wkipedia:
"The song relates how tension between Dylan and Suze Rotolo came to a head in the last week of March 1964 with a violent argument, in which Dylan and sister Carla shouted abuse at each other."
It's probably the most bitter song about real people along with "Positively 4th Street" in which Dylan flips off all the people in the Village who fed him, let him sleep on their couches and loaned him money, records and instruments while he was gaining fame, and "Like a Rolling Stone." Dylan could do bitter.
