I've found an old interview from Klark Kent for dutch television. I guess it's from the year that the album "Klark Kent" was released in the Netherlands (1980?). The interview is very short and it ends a bit abruptly because of a wrestling by which the interviewer takes of the mask of Klark Kent.
As I remember correctly Stewart's painted face was shown on tv after he lost the mask.
Please notice: it's only audio, no video! (I used to tape the mic of my cassetteplayer to the speaker of the television )
