I've discussed my affinity for the movie before so I won't go into it further. Even if you don't feel like watching 90 minutes of Teri Garr and Frederic Forrest complaining about one another while bathed in garish Las Vegas neon then at least seek out the fantastic Oscar-nominated soundtrack by Tom Waits and Crystal Gayle. I've included "Beg Your Pardon" to be listened to below, my favourite from the film. Trumpets are such an underused instrument (er, random I know, but totally true).
I tried finding a clip of the mid-film musical number, but alas it doesn't exist on YouTube, which is a shame. It's the exact sort of balls-to-the-wall craziness that endears me to the movie. Bliss.
