Well anyway, here from 1971 or so it's the very timeless "Ladybugs' Picnic"!
Few items of interest about this clip. Firstly, that's legendary muppeteer Jerry Nelson singing, with fellow muppet operator Richard Hunt playing the kazoo.
And it's also worth noting that this was animated by Bud Luckey, who is currently an animator at Pixar. Just think: this cartoon is from a guy who went on to work on stuff like Toy Story, WALL-E and a bunch of other Disney/Pixar movies.
This song was always memorable to me for some reason. At one point it was seriously stuck in my head. So now I'm showing it to you guys so that you can share my, errr... enjoyment :-)
