When I hire musicians, I look for that first: every time they sit down do they go for it, you know? And do they try to learn the music and try to get inside the song whatever the tune is? Whether it's my originals or someone else's, it's just whether or not they're gonna play their hearts out, first and foremost.
I've written about Powers Hapgood. He was a Harvard graduate, son of a wealthy family who owned a cannery out there. After leaving Harvard, he went to work in coal mines and then was a CIO executive when I met him there, in Indianapolis.
