Name this instrumental from "I Shot Andy Warhol"

I know this isn’t much information to go on, but I’m desperate. Last night, I watched the movie “I Shot Andy Warhol”. During the movie I heard a great song that I’d heard many times before. It’s an instrumental jazzy type song that is played when the main character goes to the first party at Andy’s factory. I tried to see the credits at the end of the movie and am in the process of researching each song, but that’s very time consuming.

The song is a brilliant instrumental and has a jazz sound to it. That’s all I have.

I don’t remember the specifics of the film, but looking at the soundtrack album the only song that I would characterize as jazzy is “Mais Que Nada” by Sergio Mendes & Brasil 66. It’s not an instrumental, but it does have a hard-charging bossa nova jazz piano break, could they just have used that bit in the movie?
