I'm not sure if they do this now, but a while ago Monster Jam would sometimes play theme songs for the monster trucks during their freestyles. Most of them can be found on YouTube, but one is seemingly lost.
From 2009~2013, there was a truck sponsored by Disney XD. There's a video that says You're Gonna Go Far Kid by The Offspring was the theme song for the truck despite it never using that song. The actual theme song has never officially resurfaced, with only low quality footage from old freestyles existing of the track. There is a cover by the YouTube channel ToonRaider, but the original song has yet to resurface.
