"The next time Dylan played nearby, he invited Jobs to drop by his tricked-up tour bus just before the concert."

"When Dylan asked what his favorite song was, Jobs said 'One Too Many Mornings.' So Dylan sang it that night. After the concert, as Jobs was walking out the back, the tour bus came by and screeched to a stop. The door flipped open. 'So, did you hear my song I sang for you?' Dylan rasped. Then he drove off."

Another bit from that Steve Jobs bio.
