United Airlines tune

[ual737]

I guess this would be appropriate for the off topic section, but if it should go somewhere else, let me know. I know that United's theme song is "Rhapsody in Blue", but regarding this I have a question. I was initially trying to remove the vocals, but it clearly did not work, but I want that block of the song they created for the commercial. Any help of any sort here?

If you do a Google search on George Gershwin you can find many different version of the tune.
