Throughout the poem, Trower examines how jazz music unifies the older generation fans with the new generation of young punk rockers. In the last paragraph, Trower writes that the "cardboard boundaries are erased" after the two different groups of people listen to harmonious jazz music in the same club. Throughout this paragraph, Trower explores the theme of unity through the punk rockers' reactions to the jazz music. On the surface, the older generation of jazz fans has nothing in common with the young punk rockers. Despite their differences in appearance, there is a common attitude and preference for jazz music. At the end of the poem, Trower depicts how jazz positively influences both groups of individuals and unites them through their common affinity for jazz music.
