"There was no keyboard player on the planet more appropriate to support Jim Morrison's words," Densmore wrote on TwitLonger about Manzarek.

"Ray, I felt totally in sync with you musically. It was like we were of one mind, holding down the foundation for Robby and Jim to float on top of. I will miss my musical brother."

Krieger posted the following on his Myspace page on Monday, "Ray Manzarek and Jim Morrison were the two most unusual people I have ever known. It didn't take long to realize this about Jim. He was obviously a genius, and he worked hard at being different. Did a good job of it too.

"Ray on the other hand, was a late bloomer. I guess it took all of his [and our ] energies to keep Jim in line. The real Ray didn't appear until after Jim was gone. He was constantly doing projects with different people, producing, playing with different poets. He always saw the good side of people, and that was his genius. He was the only guy at UCLA that saw something good about Jim. Everyone else thought of Jim as a phony or worse. He saw the genius of Jim's words and the rest is history.
