AARP Live is a program on RFD TV, but AARP streams past shows on demand for free. See http://www.aarp.org/tv-radio/aarp-live.html
Being an old farm boy and country person, I used to love watching RFD TV when I had DirecTV. Miss the heartland programs. Supposedly RFD is working on a Roku app which is what I use. RFD is available for streaming through other devices and PCs for a monthly subscription. Loved the old diner country music shows and past train reviews.
Of course now the AARP channel focuses on really old stuff like, Star Wars, Phasers and computers.
