Need help with 70s TV show
I remember watching it as a kid late 60s early 70s.
It ran in the mornings , maybe only on weekends , or Sunday specifically.
It had an animated intro with a song that contained the words “ just around the corner , maybe a mule eating cactus...” That’s all I remember . It may have been an educational PBS show. btw, this was in The NY/ Ct area.
Thx
