DKMS, the world’s biggest non-profit bone marrow donor center, will be holding a bone marrow drive in cooperation with Disney Theatrical Productions, and the cast and crew of “The Lion King” in honor of their fellow cast member, Shannon Tavarez. Eleven year old Tavarez is one of the many patients badly in need of a bone marrow transplant due to acute leukemia. Tavarez plays the role of young Nala in the Broadway production of “The Lion King” which takes place at the Minskoff Theatre.
