Well there was this show which I think was on ether abc or bbc and I am trying to remember what it was called, all I can remember in the show was: In the intro there was this giant turtle swimming through space which looked like it had a flat world on top of its shell and some Arabic kind of music playing, also there was a magic guitar and a musician who took up playing it and recruited a saxophone playing gnome and some stone man playing some other sort of instrument, the grim reaper was also in this and had a niece who was in some sort of orphan house, I also remember being told that this series was originally based on a novel. If you do know what show I am talking about then I would appreciate it if you can tell me the name of it.
