From Wikipedia: Davis proved, perhaps, to be the most pivotal instrumentalist during these sessions. "If you listen to the album, every tune is led by Richard and everybody followed Richard and Van's voice", says Merenstein. "I knew if I brought Richard in, he would put the bottom on to support what Van wanted to do vocally, or acoustically. Then you get Jay playing those beautiful counter-lines to Van."[22] Davis was not impressed by Morrison, not out of disdain or any preconceived notions, but rather because Morrison's professional comportment generally did not meet Davis's expectations. "No prep, no meeting", recalls Davis. "He was remote from us, 'cause he came in and went into a booth ... And that's where he stayed, isolated in a booth. I don't think he ever introduced himself to us, nor we to him ... And he seemed very shy".[18]
