My son was watching The Backyardigans - "Tale of the Mighty Knights" and the music sounded like a rock opera done Queen style. Complete with music that mimicked the middle part of Bohemian Rhapsody (i see a little silhouette of a man), We Are the Champions and Queen II.
I am not saying that Queen music was used but they definitely influenced the score. Maybe even a bit of Rocky Horror Picture Show,
Adam Pascal does the vocals on the main song.
It was a pleasure to watch (err, listen ) to it.
A bit of it can be heard at: http://www.youtube.com/watch?v=I92rJPBIoas
Although it is not as Queen-ish as the rest of the show.
