The guy, Masato Shimon, is a legendary anime singer. He is considered to be one of the top singers beside the late Ichiro Mizuki and Isao Sasaki. For the people above 50 years old, his voice was heard everywhere when they were kids.
If I remember correctly, CD was not in the market when Taiyaki kun became a big hit. There were two types of record, namely, EP and LP and the former was for a single tune.
