If you're talking about the song they play in the previews
for the film, that is called the "Yoma Counting Song". I
don't know the artist who does it, but it is LOOONG out of
print. I know because I've been looking for it for years. I
do have a passable CDR copy of it made from the preview
that I could be persuaded to share. ^_^  On the other hand,
if you have a writable CD drive and want to make one on
your own, the Yoma preview can be found on the first run
Shuten Doji tapes. (That's where I took my copy from.) Or
try any other old ADVision tapes except Cutey Honey.

If you run into a place you can get an original copy of
this song (CD, vinyl, tape, anything!), please let me know!!

Many Sharp Smiles,
--Drac (who treasures her Yoma promotional poster that has
        the Counting Song's English lyrics on it!! ^_^)
