I even wrote a letter to England to get rare material about her. Her breast reduction dang near broke my heart. 
Back in the mid-1970s I had several clients who ran "arcades", a term applied to adult stores that had booths that ran 7-to-8 minute "loops" of various kinds of sexual activity. When an arcade owner had doubts whether he might be charged for stepping beyond "community standards", he would have me review the loops. Most were not stimulating at all, and after I'd reviewed an hour or two, I wouldn't even like porn any more. But this guy brought a couple of Clyda's blowjob loops that were really good. Not just that fabulous body, but she must have been working with a boyfriend, because she gave him the best kind of service, ending with a fantastic swallow. I tried to hang onto one, but the distributor wouldn't part with it, alas. Her later work (the customs movie, and the rock groupie movie) were a mere shadow.
