In the seventies (?) eighties (?) a German Heavy-Metal
group called "Accept" used a snippet of a old German folk
melody in the intro of a song called "Fast as a Shark."
Apparently they intended for it to be a funny contrast to
the screaming metal assault on the eardrums which followed, but
the song had some WW2 connotations of which they were unaware at
the time they recorded the album.

Recently, I heard that same German folk melody again, during
a scene from the movie "Schultze Gets the Blues." The chorus
of the song goes something like "Heidi Heido Heida" and if it
has any other lyrics, I've never been able to make them out.
Connotations notwithstanding, it's a very infectious little
melody and I have had absolutely ZERO success in tracking
down the name of this tune. Can anyone help?
