I used to love this show as a kid. I remember many Saturday mornings watching the adventures of these guys, along with Frankenstein Jr.
I grew up loving the Hanna-Barbera heroes and recently decided to watch them again. Amazingly the show I liked least as a kid(this one) is the only one I can even bear to watch now.
Frankenstein Jr and the Impossibles were my favorite show. I just wish they did play the songs of the Impossibles in their entirely.
