I Can Hear Music - an alternative history for Carl Wilson

Carl Wilson of the Beach Boys was the group's diplomat, peacemaker and undisputed 'glue' that held the band together. He was also a hugely talented, greatly respected and much loved musician who did not get the recognition he deserved when he was alive.
Sadly he died at the age of just 51, when he had so much more music to make.
What if things had been different? This is my alternate history for Carl.
