Not sure if this would be a People Sit on Chairs
trope. Doesn't seem like it would to me.
A self-explanatory trope. This is exactly what it says on the tin: a show changes its Theme Tune
at some point within its run. This does not refer to rearrangements, but rather outright replacements of the theme.
- Wheel of Fortune used an Alan Thicke tune called "Big Wheels" until 1983, when it was ousted for "Changing Keys", composed by show creator Merv Griffin. "Changing Keys" was re-orchestrated several times (with Merv having little to no hand in the last two remixes) until the theme was finally retired in 2000 for an unnamed theme by Steve Kaplan. And that theme was retired in 2006 for the current tune, "Happy Wheels" by Frankie Blue and John Hoke.
- The Joker's Wild started out with Jean-Jacques Perry and Gershon Kingsley's "The Savers". Over time, they used a Jimmy Hart Version composed by Alan Thicke, a re-orchestration of "The Savers" by Hal Hidey, a new theme composed by Hidey, and even briefly used another Perry and Kingsley tune. What's more, they also stole the theme from Break the Bank for a tournament of champions.
- The Drew Carey Show. Drew's own "Moon Over Parma", "Five O'Clock World" by the Vogues and "Cleveland Rocks" by the Presidents of the United States of America.
- The Unit. First "Fired Up", then a different tune by the same guy (perhaps because "Fired Up" was adapted from a Marine Corps cadence and therefore not a good choice for an Army-based show).
- In season 4, Big Love changed from "God Only Knows" by The Beach Boys to "Home" by Engineers.
