Whenever someone dies at age 74, I get curious. As I often show, 74 is highly connected to '33'. In this case, William's fame comes with his relationship to Gladys Knight and the Pips.
Gladys = 7+3+1+4+7+1 = 23/32
Knight = 2+5+9+7+8+2 = 33/42
Gladys Knight = 56/65/74
Gladys = 7+12+1+4+25+19 = 68
Knight = 11+14+9+7+8+20 = 69
Gladys Knight = 137 (The 33rd Prime Number)
Pips = 7+9+7+1 = 24/33
Notice the photo is from '96 and the word Freemason has gematria of 96. Of course, '33' is the number of obsession for the Freemasons.
As for her green outfit, it also ties nicely to her name gematria of 137.
The name 'Gladys Knight and the Pips' also has a gematria connection to 'Zionism' and 'Masonry'. We know how these entities control the music recording industry, and how they also kill their musicians by the numbers, often after retirement from recording.
In history, William Guest was born 23-years to the day of the 1964 Civil Rights act. He was born on the 33rd Parallel, in Atlanta, GA.
He died 175-days after his 74th birthday.
