I'm assuming that these are just Lindsey's instrumental PERFORMANCES.
We DO know that Lindsey didn't WRITE "Django", right? (if so, just to be redundant) It was written by legendary jazz pianist John Lewis of the "Modern Jazz Quartet".
My vote went to the intro to "Don't Look Down". Probably has something to do with the melody being EXTREMELY similar to those that blasted from those gritty speakers atop the Good Humor ice cream trucks that used to cruise through the neighborhood back in the 50's & '60's.
