One of the classic cases of dubbing is Barry Manilow’s “One Voice”. All 40 of those voices are Manilow himself.
I'm kind of a ditz when it comes to performers. They either come to my attention and captivate me, or I don't bother with many of them that were hugely popular.
I heard of Captain and Tenile but not Darryl Dragon and don't know a thing about them.
As to Jung, I did find him more interesting, but he seemed to be an occultist. I do believe in the concept of the collective unconsciousness but don't know if it is valid. This could be ridiculous, but I believe Christians if they have reached a certain level of spirituality, not that they have worked for it, are freed from being entrapped in that. For God's purposes, He most certainly could impart whatever knowledge, gift or sensing to a soul He wished.
The reason I came to believe he may have tapped into the occult is t hat he had an OBE where he describes himself as halfway to the moon at an incredible speed.
I tend to have a habit of trying to simplify philosophical concepts that are hard to understand and I might be more open if it hadn't been for the nihilists and what followed.
