Mars is Conjunct Antares (the Violent Star)....good for the Military but prone towards inviting violence into the life.
Apparently this fits well, from what I've read of his more violent side....showing up at Elvis house, with a gun, that the Security people needed to call the police to remove him.,and other such episodes.
This (Mars 9Deg.Sagittarius,conj. Antares) would explain this trait in him.
I just noticed he has Algol conjunct the I/C.
The I/C is the home life , the place of our beginning of life and the place of our ending.....We look at the I/C or 4th house cusp & 4th house to see how the early psychological beginnings were, whether they were upsetting times (Uranus and/or Pluto)....or whether the background was full of love & care (Venus perhaps or Jupiter)
In Jerry Lee's case, Uranus in the 3rd House also shows us his manner of communication was unique and different.
Uranus can mean a kind of genius, but in the lower vibrations also depicts upsetness and much turmoil.
The 4th house of early home and mother has Chiron here..the "inner wounding", thus the home life for him will be full of pain (all the break-ups and the deaths, divorces and separations)certainly must have been felt over the years as very painful experiences in the home (4th)
The 6th house, I've not yet grasped as I'd like to.
We call it the House of our Health, and the house of Service to Others, but from what I've heard, the 6th house is also a house which can depict sorrow in life. The Vedics seem to think it's a troublesome place.
Pluto here then, may say more then just about health, as it's between the 5th (lovers & creativity) and the 7th (Marriage & committments)as well as "open enemies"....
Yes, I think the 6th has more meaning and symbolizes more here with Pluto.
Another "key" to his life and turmoil, would be the South Node in the 6th house which doesn't show on the wheel, but is always across from the North Node (in this case in the 12th house)
To have the South Node near Pluto, is bad. No two ways about it, just as having the SN (conjunct to Saturn), making it two malefics.
Pluto is harsh......SN is also harsh as it is of the past energies, (past lifetimes, and we are supposed to be moving away from the past into the future or the NOW"
It's not a close connection , but within 8 degrees, so probably the Pluto in the 6th & the South Node shows us there is kind of a devilment that plagues him....
If you read the biographies posted you see in Wikipeida, he told people when young, that he "plays the devil's music for real".....or rebels against his parent's early church fundamentalism...
This is a good depiction of Plutonian energy with South Node .
Someone determined to upset the apple cart, someone determined to be bad, just for the sake of being bad.

POF (Part of Fortune), 0deg.PISCES - conjunct Saturn.
Again the fortune in the life connected to a Malefic, i.e. Saturn or "Lord of Karma" more appropriately called.
to sum up:
The difficult life of a driven man known as Jerry Lee Lewis might be seen astrologically by the following driving forces in his psyche:
1)ALGOL (a huge force for evil and upset in the life) at the I/C
2)MARS (physical energy) conjunct ANATARES (Military sign)9SAG.
3)Mercury 0Scorpio and the Moon in the Anaretic or 29th Degree of Libra ..........neither position here is optimal for a peaceful and harmonious life
4)JUPITER: 21 deg.Scorpio, (I have this position in Jupiter as well)
and I promise you it lives up to it's reputation.
The reputation for this degree of Scopio, is "A Definite Loss"
Now this can be either literal (as it was for me), or symbolic, (as I think it is for Mr. Lewis)
For me, it was the definite loss of a child.,in the 5th house of Children
For him, it falls on the 10th house cusp, conjunct the M/C which suggests then, that it is opposing Algol at the I/C
So the "bad effect" is worse then.....quite bad, and the life lived is a testament thus far (all the losses all the divorces and deaths)in one family.(his)
His Saturn is Retrograde in the natal......so karmically, he "repeats" the same lessons as before.
Now IF his posiition was 3PISCES intstead of 4Pisces, it would be a dead ringer conjunction with the Fixed Star "Fomalhaut" a Persian royal star known for "making a name which is immortal"
I think this still fits for him, as it did in fact auger an "Immortal Name".......and is only one degree away from the present location of Fomalhaut.
so it's in line.
