Valerie Harper, Mary Tyler Moore, Cloris Leachman join 'Hot in Cleveland' for 'Mary Tyler Moore Show' reunion
Deadline reports the episode will tape April 5 and involve Elka (White) and Mamie Sue (Engel) organizing a reunion of their bowling team nicknamed "GLOB" (Gorgeous Ladies of Bowling). Moore, Harper and Leachman will play the other members of the team.
"Cleveland" frequently books TV veterans as guest stars -- and Moore did a Season 2 spot as a tough prisoner when Elka went to jail -- but this is the first time the quintet of "MTM" veterans will act on screen together since that show's 1977 finale.
The reunion follows Harper's announcement she is living with terminal brain cancer.
Just yesterday TV Land renewed "Hot in Cleveland" -- which also stars Valerie Bertinelli, Jane Leeves and Wendie Malick -- for Season 5.
