I always had mixed feelings about this song. Its got a great tune, a great country sort of feel, and its really catchy. On the other hand its a country hippie song about smoking pot, and I never really appreciated that part. But one thing I know for sure, these people had no clue what it was about.
That really happened, in 1971. This is not a hoax, not a clever mashup, this is not a faked version. They really sang this on the Lawrence Welk show.
