Yes, that is Dr. Hubbard singing.
TRUE TRIVA: Little known fact. Dr. Hubbard composed
and played the organ solo on the Doors mega hit
song: "Light My Fire".
Shhhh, that information is strictly not BPI and is "need to know" only.
We wouldn't want on purpose staff and public thinking they can pursue their interests or talents in music.
Ron notated Light My Fire in three seconds while on a research break. Had his organ delivered to his office and played and recorded the demo on one hand while adjusting a PC's TA with the other.
The rest of us can do music next lifetime, after the planet is saved.
