The Uncomformity

I have located an apparent anomaly in the geotemporal record. If Searly really had a close acquaintance with Captain Beefheart during the timeof pulse diet adherence, this could not be the same searly as the teenage poet who released Octopiithagoas in 82.
Or could it?
Two possibilities occur to me, which could maintain the supposition that both events occured and involved the same man, without upsetting the timeline with anachronicity.
The first is that a much older Searly entered the poem in thecompetition. If so, the psychological profile of Searly would change - a 25+ yr old writing such a poem, or just entering such a poem that hemay have written while teenage, would be a very different person fromthat envisaged before, perhaps a late developer, or an individual havingthe syndrome which results in childlike (or in this case teenage) tendencies and mentality into adult life.
(Or alternatively, the poem may have been written by a teenage Searly and entered by someone else who had acquired the poem. I personally dismiss this for now.)
The second possibility is that a teenage Searly did write the poem in 82, and an infant Searly spent time with Beefheart in say 69-72. I imagine a 2 year old Searly telling the captain 'no, captain, don't do it that way...'. The influence of a 2 year old Searly could explain much of Beefheart's output during that period.
