People who know the band well...what do you think?
Here are my best guesses:
Robert: ENFJ (He was definitely very outgoing. Many of his lyrics are metaphorical and emotional. I am pretty sure he is a J based of his temperament in interviews/books etc)
Jimmy: INTJ (He was very shy. I think he is Ni dominate because he was really into the occult and very mystical. He was also very single-minded and organized in his approach to his music. He had very specific ideas for the band and held it together. He also contributed to the production of the music)
Jonesy: ISFJ (He was the quiet one. He really held the band together musically and was a technically/creatively talented musician. He generally did not go along with the bands antics.)
Bonzo: ESFP (I think he was really naturally talented and really felt the music. I am not so sure about him as far as temperament though he loved to drink/party)
