One of my most essential bootlegs of all time is Neil Young playing a surprise set at the Bottom Line in New York in 1974. While the audio quality isn't great (it's an audience recording), the performance is outstanding, and represents one of the earliest performances of songs from On the Beach.

They've only played Natural Science a handful of times on the tour so far, and they only play 4/7ths of 2112.

Technically Voyager 2 was actually sent first, but that doesn't make for a very good joke…

They did. It was called Voyager II.

The sign on the train clearly said "Not In Service".
