Panopticom, yes they are used in prisons, so that they use less prison guards and prisoners never know for sure if they are being watched and the idea is they behave better. Interesting song by Peter Gabriel, good to see that he is still making music.

23 albums! Wow that is quite the haul from Jethro Tull, impressive stuff, I like this one of the album and must remember to have a listen when it is released.

Nice finish to the set with Gentle Giant who I have never heard of, but liked that tune.
