SHUFFLE ALONG on Bwy-Overflowing with Talent but A Triffle Long

Actually, SHUFFLE ALONG, is more than a tad too long.  And, despite its incredibly talented cast, the historic story telling implodes as it straggles with convoluted intentions.   The trifecta of talent, singing, dancing & acting in the company was astounding.  The cast was comprised of 6 time Tony winner, Audra McDonald, Brandon Dixon in a brilliant performance of Eubie Blake, Brian Stokes Mitchell, Billy Porter and Joshua Henry.  Adrienne Warren played dual characters Gertrude Saunders & Florence Mills was sensational.  The entire ensemble was superb.  Jelly Roll once said "Get up from that piano you hurtin' its feelings."  My dilemma with the continuous show stopping numbers was, I wasn't sure what I was made to feel.  Learning about the legendary musical geniuses & the struggles to stage the 1st all black B'wy musical in the early 1920's  should make a compelling, contemporary production.  But, the show was too ambitious & far reaching to fully register the historic impact & the brilliance of the numerous musical numbers choreographed by the legendary Savion Glover.  Is it possible that this show suffered from too much of a good thing?  Eubie Blake wrote the compositions  "Troublesome Ivories" and "Memories of You."  There were snags with how the show moved along.  Most troubling of all was the meanspirited number where the only white cast member gleefully sang nobody is going to remember any of you groundbreaking musical giants.  The finale deflated the overall high energy with self-eulogies given by the stars.  I will remember with love the stellular singing & dancing but the show left me with an overall befuddlement.
