There is no good time for a full-fledged rock icon to lose their mainstay bandmate and musical director. Certainly not in the middle of a world tour, or just before the long-awaited bio-pic of your life is to be released.

How do you fill the shoes of the performer (and creator) of the slashing electric solos and lush acoustic layers that helped define so many Elton John classics? You call John Jorgenson.
