Imagine the Rolling Stones' classic "You Can't Always Get What You Want," sans the embellishments of the London Bach Choir.  Definitely doable, in my opinion.  Ponder the Beatles' "The Long and Winding Road," minus the Phil Spector-imposed orchestral strings and choir of angels. Totally preferable. Contemplate Bob Dylan's landmark "Like a Rolling Stone" without  those haunting, no-direction-home Hammond organ chords. Absolutely inconceivable. Had it not been for the gutsy gamble of a 21-year old named Al Kooper, Dylan's decade-defining anthem would lack much of its signature, soulful sound. The great Mr. Kooper turned 70 on February 5, 2014.
