LOST? Hardly
From The Lost Media Wiki
Disney has all the masters and probably other materials in their vault. The show was an amazing production. Each show featured totally new songs, cartoons which were re-produced with new character voices, sound effects, and musical scores. The series was a big hit in the UK and Europe and well received in the US via cable TV. Musical Director Andrew Belling recored all the music, wrote many of the songs and recruited a bevy or talented song writers around Los Angeles.
