This show is on Teletoon Retro all the time. I love it, even though I think it is possibly the crappiest, low-budgetest cartoon ever. The movements didn't sync up with the audio, they reused the same three backgrounds over and over, and the plot didn't really make sense. But it was still awesome 8)
Rocket Robin Hood was my first experience with the legend of Robin Hood, I watched the show in the late '70s & early '80s.
I didn't even know Saturday morning cartoons existed. The only cartoons I knew about were:
Rocket Robin Hood, Hercules, Spider-Man, The Flintstones, Popeye, and the various holiday specials.
However, in the fall of '83 is when I was first introduced to Saturday morning cartoons, and I was hooked!
