“California Girls” is one of my favorite songs.It loses its appeal, thinking that Brian Wilson may be on tour when he’s 95 in 2037 holding a microphone in one hand and holding on to his walker in the other.Obviously I’m not jazzed or thrilled about the upcoming Beach Boys 50th reunion tour. With all due respect to Brian Wilson, at age 70 it’ll seem more like my grandfather singing than someone whose music and songs were the gospel to California sand and surf aficionados in the 1960s.There’s nothing wrong with singers continuing to ply their trade as they age. But it does tarnish the image of both their songs and their stature when their voice and bodies no longer fit their old standards.If I had to pick one singer who has more songs than anyone else that I list among my favorites it would be Frank Sinatra.
