The "List Of Speed Racer Episodes" Clip Is Lost Again...
From The Lost Media Wiki
It's worth noting that the "List Of Speed Racer Episodes" clip is currently lost again as the account that posted that video was terminated around 2019. Viewing the video link on the Wayback Machine we can see the video was posted on February 26, 2014, with the description reading "Girl wants to know about the Speed Racer episode guide." if that helps. Edit: Could this be it? https://www.youtube.com/watch?v=wsjDxW1CJvk
