Spectrum has what appears to be the final interview with Arthur C. Clarke, conducted in January of this year (while Clarke was in the hospital). Clarke discusses geo-stationary communications satellites, space elevators, and his thoughts on private-sector space travel. It's an interesting dialog with a futurist and visionary who lived to see some of his predictions come true, most notably the satellites (space elevators are still a ways off).

Clarke gave few interviews in his later years, so the Spectrum interview is well worth a listen.
