So serene, so measured, so lovely. The boys make their way through Brian Wilson's stately stair-step melody like they've got all the time in the world. I guess they didn't. Two of the Wilson brothers, Dennis and Carl, are dead now. But I would bet that when the remaining Beach Boys gather to sing this, they feel young again. Or maybe not young, but like ageless residents of the Tower of Song.
Just a thought: Why don't more (any?) jazz and classical musicians create orchestral arrangements of Beach Boys / Brian Wilson classics. I could hear a lush arrangement of "Surfer Girl" with endless variations -- composed and improvised -- spinning off the main melodic motif.
