So this is something I'm in the hunt for that was part of the Mr. Men Show that was never used in the show, but was actually made.
There was a song the show did that was their take of "Ta Ra Ra Boom De Ay". I know this was real as I remember it was on a YouTube channel back in 2009 that posted some rare Mr. Men Show content such as storyboards. I decided to contact the composer of the show Jared Faber if he remembers, and he does, but he doesn't know if he still has it or not.
I'll try and contact other staff members of the show if they have a copy of this song or not. If anybody remembers this, did you managed to save this video or have memories on it?
