Very briefly. My very first game was AD&D1. I played a thief. The game last all of six sessions, each an hour long, and then it ended when the DM disappeared. I later learned that he'd gone to university, and ran out of free time when the term started.
After that, I DM'ed BD&D from the Red box (through as far as the Companion set), for eighteen months, then moved to 2nd Edition, to 3rd, and then to 3.5.
