One of the episodes of Revisionist History talks about genius and
different types of innovation, through the episode they talk about
Cohen and how his song Hallelujah was not an overnight success. Cohen
worked on it over 5 years to get it to a point where he was
comfortable with!
Dylan is also mentioned in that episode, since they had some kind of
mutual admiration. Apparently Dylan and Cohen meetup at some point
and Dylan asked Leonard how long it took him to write Hallelujah and
he lied saying "2 years". Then Cohen asked Dylan how long it took him
write "I and I" and Dylan said: "oh, like 15 minutes".
