Some old hippy song
 

Saw it on tv a few months ago, was kinda fun, nothing special but cant shake it from my mind.

In the music video we see all sorts of people in a backyard or something going around in a circle. They look hippy like and they all sing the same song when its their turn when the camera is pointed at them, they take turns in singing. Its hard to explain. The clip is very simple and goes on the same way throughout the entire video.

Can you explain the song? I don't know the commercial. Any words? Instruments?

That description made me think of this, even though it doesn't tick many of OP's boxes, especially not the "old" one: the song is from 2013, but is very retro-hippy in style:-

Do you remember any of the lyrics?
