CQ-7027: Umi no Triton Theme Music Collection

[depa]

Two question:

1) Is "Toriton of the Sea" officially somewhere in Japan instead common english people name "Triton of the Sea"?
I found only official japanese Pioneer DVD with international title
edit: this EP give Toriton
Maybe they are both OK

2) for anisonfan who own this LP, is there コルゲンバンド "Colgen Band" credit somewhere in the insert?
From the scan we have it seems not, but in the promo white LP yes.
