'There will never be another one like you,' lyrics from 'Shaman's Blues' by Jim Morrison and The Doors.

Keyboardist Ray Manzarek died on Monday, May 20, at a hospital in Germany after a long battle with bile duct cancer, he was 74.

Manzarek's keyboards were groundbreaking. The Doors are one of the only classic rock bands without a bass player and that's because Ray could play all the bass on his keyboards as well as amazing organ riffs which were the backbone on which Jim Morrison slithered as 'The Lizard King.'

His solos on songs like 'L.A. Woman,''Light My Fire,''Riders on the Storm' and 'Love Her Madly' defined the sound of The Doors.

Ray Manzarek even added the keyboards to Weird Al Yankovic's 'Craigslist' parody.
