I may be wrong but typically they only televise the National Anthem for key sporting events ie..superbowl, indy 500, world series, etc. Regular season games seem hit or miss. If i happen to be in the room while it is sung I do stand and remove my hat. Remember how much controversy Steven Tyler caused when he changed the words or Rosanne Bar grabbed her crotch and spit? Same thing it was disrespectful. As I mentioned I may be wrong about how often its televised and I'll pay closer attention as to confirm that...
BTW: Mauigrown Coffee is pretty damn good too.
