What is the fine-grained topic of the following text: We meet the travelling showman, Crow Step Billy, eternally searching for his lost love Jenny, and whose horse can sing harmony and play the violin (Jenny's Gone for Rock 'n' Roll); That Kid Who Loves Birds, a well meaning Zen outlaw whose lost years in the methamphetamine trade have left him with a sorrowful, yet strangely hopeful, tale to tell (A Brand New pair of Riding Boots); and Fox Eye, one time trader in re-birthed cars, now hermit philosopher and dangerous stranger on the road (A Bad Night on TV). Only return the topic.
