Source Identifying 1971 Claiborne Farm Subject in Historic Photo

If anyone knows this gent's name - the shirt says "Johnny" but it may not be his shirt - I'd be interested. Trying to ID some John C. Wyatt negatives. This was shot at @claibornefarm , maybe ~1971, and there are a few shots of this gent. Might have been for a feature story. ? https://t.co/bNbWrcPNmc
