I have always loved Klaatu.. Especially the first two albums. On 3:47 EST is a tune called Sub Rosa Subway. This is about Alfred Beach, who with his own money, excavated under Broadway and in 1870 built the first subway in America. It used the same pneumatic tube principal that banks use today at their drive-thru windows. Tons of information available on the net. And it was just as described in the song, with giant aquariums, a grand piano with a pianist playing Brahms and Mozart, giant crystal chandeliers... Amazing.
Also, I particularly like the song. "Hope" It is, after all, the greatest gift of all.
