Jennifer Holliday saw Cynthia Erivo in The Colour Purple

Greetings Dear IG Fans&Friends, My Love-Affair with "THE COLOR PURPLE" continues and my love for this show has now been lifted even higher! Happy to be chosen for the role of "SHUG AVERY" and Honored to be working with the extraordinary cast of this beautiful and uplifting broadway revival production directed by John Doyle. Watching CYNTHIA ERIVO give her Tony Award winning performance as "CELIE" gave me LIFE! Humbled for this opportunity to partake of this "Ultimate Master Class"... to work with such an acclaimed broadway director as John and to learn from such a superb actress as Cynthia... PRICELESS! So THANKFUL TO GOD for "HIS DIVINE FAVOR" and For All Things PURPLE!!! Love&GreatJOY... JENNIFER
