The King's Trumpet

Mel-O-Toons sometimes erroneously called "Mello Toons", was a series of animated cartoons produced in 1960 by New World Productions and syndicated by United Artists. It featured various folk tales, Greco-Roman myths, Biblical stories, some original stories by author Thornton Burgess, classic stories, even adaptations of classical music and ballet. The soundtracks were often taken from existing children's records, licensed from the original labels. 104 cartoons, each about 6 minutes long, were produced in limited animation. -From Wikipedia
