I never seen this Banana Split stuff, but it seems pretty hilarious - as do a lot of things of that time really.
I was just 10 at the time, so I didn't actively experience all that stuff, not until a few years later. I never became a big fan of Janis Joplin for some reason. I mean, she's ok, but not outstanding IMHO.
But that only my view. It cool you also share your music picks. But there is just too much stuff that s worth mentioning really, no chance to show it all.
