One of the first Celtic Thunder shows I say on PBS was Storm. It was recorded in 2009 alongside It's Entertainment!. its release was pushed back due to the shows Christmas and Heritage. One of the songs, a duet between Ryan Kelly and Charley Bird (but the character is performed by Caroline Torti), "Outside Looking in" made me think about Blaze and Roxy, the Cybervillains (i.e. evil rangers) of Power Rangers Beast Morphers. They still have the memories of the humans they came from (which is important to the motivations of both the heroes and villains in the show).
