Classical Music @ The White House: JFK & Obama

"Now, if any of you in the audience are newcomers to classical music, and aren’t sure when to applaud, don’t be nervous. (Laughter.)  Apparently, President Kennedy had the same problem.  (Laughter.)  He and Jackie held several classical music events here, and more than once he started applauding when he wasn’t supposed to.  (Laughter.)  So the social secretary worked out a system where she’d signal him -- (laughter) -- through a crack in the door to the cross-hall".

Oh, and Tim Smith wuz there.
