I was watching a show on National Geographic about John Kennedy http://www.natgeotv.com/za/jfk-seven-days-that-made-a-president this evening, and became oblivious to what else might be on TV. But after that was finished, I started looking and realized that I missed the National Memorial Day Concert https://tv.kttz.org/schedule/#page=schedule&day=20170528&provider=Broadcast

Laurence Fishburne and Joe Mantegna host the annual salute to America's military heroes. Performers include Renée Fleming, Vanessa Williams, Scotty McCreery, Five for Fighting, Ronan Tynan, Russell Watson and the National Symphony Orchestra. Gen. Colin Powell (USA Ret.), John Ortiz, Christopher Jackson and Ana Ortiz also appear. The event features a salute to the Doolittle Raiders presented by Gary Sinise and includes a look at music therapy for injured vets. From the U.S. Capitol's West Lawn.

I was able to watch the last half hour, and fortunately, it will be re-aired. So I will get to see the show.  Thank you PBS.  Which is why I send a small donation every month.
