Very sad news. I was always fascinated with Klacto's name, but never discussed it with him. I remember the old Charlie Parker recordings on 78 rpm's from the late 40s and early 50s. Some of his more arcane recordings were "Relaxin' at Camarillo" and "Klactovedesedstene," and one that was recorded while he was breaking down that wasn't supposed to be released that my high school band teacher had. I never found out the meaning of 'klactovedesedstene,' assuming it has a meaning, or what language it is from.
I imagined that Klacto had been a Yardbird fan and we might have had some interesting conversations. But, we didn't. Bird lives. Hope Klacto, too.
