What are the motifs in This Wheel's On Fire: Levon Helm and the Story of the Band by Levon Helm?

Fear is a recurring idea in the book, although it is not as obvious as the others. Levon tours for several years with Ronnie Hawkins and the Hawks in Canada. The Hawks are very well received in Canada and they make good money there, better than Levon is used to. However, when they come back to the States they only get the same welcome in the southern states. Their fear of failure in the rest of the country keeps them from becoming all they might have been at this time in their careers.
