When it comes to literary references in other works of art, some are more overt than others. It is obvious to most, for example, that Kate Bush's 'Wuthering Heights' takes its inspiration from the Emily Brontë novel of the same name. Less obvious, however, is that Katy Perry's 'Firework' has its origins in Jack Kerouac's 'On the Road.'
