The choice of 'Over the Rainbow' with a Olivia Newton John cover I thought was a bizaree choice to play over the shootout. I think I read years ago in Premiere Magazine that the Wizard of Oz was one of John Woo's favorite films as a child so it kind of makes sense he would put it over the scene. I'm also kind of obsessed with Gina Gershon putting head phones over his ears to ONJ singing one of his favorite show tunes to put in out of the violent situation going on. A kid that takes after my own hearts obviously. I want to hear the conversation on the set with John Travolta that his old Grease costar ONJ would be doing the 'Over the Rainbow' cover over the scene.
