I think the 'girl' in this song is just Rock and Roll in general. Knopfler might be talking about how he lost track of the real music because of the crazy, glamorous, money-soaked life he leads (and in the roar of dust and diesel I stood and watched her walk away/i could have caught up with her easy enough but something must have made me stay).
