Something nobody seems to notice about that Dylan/Donovan encounter (I didn’t notice it myself the first couple of times I watched it): Donovan actually *requests* “It’s All Over Now, Baby Blue” as he’s passing the guitar to Bob! So there was no intention on Dylan’s part to shut Donovan down; Donovan already knew how brilliant “Baby Blue” was, even if he didn’t realize how limp his own offering was.
