Maisy is a British/American children's show that aired on Nick Jr. in the U.S. and the U.K., and later aired on Noggin from 2002 to 2007 and Qubo from 2009 to 2012. It has separate narrators for the U.K. and the U.S. Most of the American narrations are lost as opposed to the British narrations, which can be found easily on YouTube and other websites, though, some of the American narrated episodes can be found on DVD, while at least one episode was released on an American DVD with the British narrator.
Update: The Maisy Mouse Official channel on YouTube has uploaded all of the American narrations. This is the link to the channel:
