Thanks for the Norman Greenbaum link. I'm familiar with the song, but the video's new to me.
First psychedelic song I can think of (and I'm a big fan of the genre) is See My Friends by the Kinks (1965): https://www.youtube.com/watch?v=-Ugr0pgUo1c (the video is just of the Kinks performing the song, though).
There are plenty of videos used for psychedelic songs, but it's usually hard to tell whether the video was made specifically for the song, and most are either recent or montages of videos from the late 1960s.
Some contemporary videos (all from 1967) for psychedelic songs which are more than the just the group performing:
That Paper Sun example is really good. I like how they're shaking the camera to make the masks look like they're breathing.
And the Strawberry Fields Forever example is also super interesting because the parts with the piano are more surrealist, but the closeup shots of their faces are more early psychedelia.
