To prepare for his role as the Pinball Wizard himself in this season’s revival of The Who’s Tommy, Moroccan American actor Ali Louis Bourzgui watched every live performance by and interview with The Who that he could find on YouTube. As dedicated as that may sound, Bourzgui feels that the rock opera, last seen on Broadway over 30 years ago, “is to the classic rock world what Hamlet is to the classical theater world. It’s a timeless, legendary fable that changed the course of music in the late 1960s and then Broadway in the ’90s.”
