During their trip Coburn would always sit in the front part of the car next to the driver while Silipaht and Bruce Lee were riding in the back of the car. Bruce Lee had an interesting habit. He would constantly sing very quietly to himself as they were driving. He would sing a tune that was his favorite one at that period of time. His favorite tune was Yesterday. He really thought that all his troubles seemed so far away. However his singing really irritated Coburn until one day he blew and told him to stop singing. He told Lee that he was driving him crazy. Bruce Lee joked with Coburn that his voice was rich because it was well off. But as Coburn turned back to look at the road that stretched really far ahead, Bruce Lee just shook his fist at the back of his friends head.
