Quatermass....and The lamp In The Corner!

After watching the 1950's science fiction on iplayer last night I went looking for more on the inter web machine and discovered a rich vein including all three original Quatermass series. I've seen the movie versions of The Quatermass Experiment and Quatermass and the Pit many times and discovered the movie version of Quatermass 2 on iplayer but I'd never seen the original tv series before, indeed I didn't think complete copies existed as they were broadcast live at the time, but somewhere (probably an export copy) survived, filmed from the tv screen (this was all before video tape) and now put on You Tube....I was transported!
