it's somehow hard to image, but -

Leonard Nimoy while playing the the ultra-
logical, emotion-suppressing Spock on TV's
Star Trek was
 
writing, singing and recording emotionally
charged love songs in real life

between 1967 and 1969 Nimoy released
three albums on the Dot Records label:

The Two Sides Of Leonard Nimoy
The Way I Feel
The Touch Of Leonard Nimoy

the soundtrack of the video below features
Nimoy singing, I'd Love Making Love To You
