i just looked in my copy of Interpid 18/19 and it is the exact same poem and it is called that liberating movement in the magazine. The database has a typo.
The poem that was shown is obviously a carbon copy and he has having trouble with his typewriter. i used to have a poem carbon like that, but had to sell it. I believe that it dated to the late 60's, early 70's... The fact that it was published in 1971 fits with that time.
