I was reading Sting's
Shigeki Hayashi was
apparently Koji Hayama's disciple.
A bit of googling to recheck and yep, according to
this message by Hayama his disciple 林シゲキ (Shigeki Hayashi) went to Sting.
Since this album was partially composed by Hayama, no doubt SHIGEKI = Shigeki Hayashi. Most curious.
