You will search, babe
At any cost
But how long, babe
Can you search for what’s not lost?
Everybody will help you
Some people are very kind
But if I can save you any time
Come on, give it to me
I’ll keep it with mine

“I’ll Keep It with Mine,”·a heartbreakingly lovely solo performance on piano and harmonica, did turn up on Biograph, after sitting in the vault for twenty years. How can Dylan record something so beautiful and then let it remain unreleased? This is a question that gets asked again and again, which is why so many people collect Dylan tapes or buy boodlegs (illegal, unauthorized) Dylan albums.
~Paul Williams (Bob Dylan Performing Artist I: The Early Years 1960-1973)

And what an exquisite song it is. Author Paul Cable once described “I’ll Keep It with Mine” as “possibly the best thing he had written up to that point . . . [while] the lyrics form the least patronizing way I have yet heard of saying, ‘I’m older than you—therefore I know better.’” In just three verses, bound to a three-line refrain, Dylan manages to encapsulate so much of what he had been hoping to say in the trio of songs to Suze. In her case, though, he hadn’t got beyond his tangled feelings long enough to whisper words like, “If I can save you any time / Come on, give it to me / I’ll keep it with mine.”
