Heino und Jerry im Uber Space has posted The Electric Lucifer coupled with some fantastic images and some lovely YouTube clips featuring our Mr. Haack in the presence of one Fred (Mr.) Rogers. I knew I loved that program. (For those not in the U.S. Mister Rogers' Neighborhood was a long-lived children's program on Public Broadcasting Service that featured some great things for kids and their parents.)
At any rate, check it/them out. Highly Recommended!
