Texas Longhorn

He went by the stage-name "Texas Longhorn" and was a big deal in porn circles in the mid-late 70's. Never did much video (beyond a couple shorts like this) and showed up in a few mags, once even in Hustler I think. He certainly had John Holmes beat on length, but his dick had a strange shape (got MUCH thinner from the base to the head), could be just because he was monstrously long. In any case, either because of a physical situation, or just his state of mind - couldn't "get it going" on camera or in front of an audience. People were certainly plenty happy just to look at it swinging around though.
