Golf Journal by John Paul Newport THE MADNESS IN THE METHOD.
Page W4. 2nd paragraph: "but nobody would confuse Stack and
Tilt with the swing detailed in "The Golfing Machine," a thick 1969
instruction manual by Homer Kelley which also has many devotees
on the PGA Tour, including most avidly Steve Elkington." Lots more
to read.

Very good article well worth reading.
