Today's music: The Beach Boys write a song on the day JFK died

Fifty years ago today, after learning that President John F. Kennedy had been killed, Brian Wilson and Mike Love of the Beach Boys got together in a hotel room and finished writing a ballad they had been working on.

In an interview, Mike Love talked about how he came up the lyrics. "The melody was so haunting, sad, melancholy, that the only thing that I could think of lyrically was the loss of love," he said. "Though I wanted to have a silver lining on that cloud so I wrote the lyrics from the perspective of, 'Yes, things have changed and love is no longer there, but the memory of it lingers like the warmth of the sun."
