I remember hearing this a lot in 1972, not much since then. I seem to recall that it was a concert recording; however, I am unable to find on what album. Does anyone know? Also, I recall the lyrics slightly different, such as "lights under the skirts". What was great was when he said "with windows you can see out", and then changes inflection to emphasize "can't nobody else see in". I thought also that there was a reference to a "whip aerial" and maybe a spotlight.
