Some of my sources:

And my own CD and booklet.
Night Hawks, the vocal leader Shuichi Aoki and the others members of this rock band are written in Romaji in my booklet.
I know very well Night Hawks (and Shuichi Aoki too), I have all their CDs, it is one of the best AOR Japanese band for me (in the late 80's / early 90's). And I have discovered justly Night Hawks, with their songs for Fuma no Kojiro.
Also, Toshirô Imaizumi's artist page is here:

I have well the same kanjis in my booklet.
