A few fun facts...
Morrison was a HUGE fan of Frank Sinatra and his voicing.
When the Doors walked into Sunset Recorders for their first album, Morrison's eyes immediately spotted a Neumann U-67 microphone, a legendary classic that was world renown for its' amazing midrange detail, ultra-low distortion and smooth sound quality...and it used a Telefunken vacuum tube to achieve that magical sound.
Morrison knew the U-47 (and later the U-67) was THE microphone Sinatra demanded be used in his recording sessions...and he got excited excited knowing he would record his vocals into the same mic used by Sinatra.
The Neumann U-67 was also famously used on the piano for the Beatles' "A Day In The Life".
