I am always skeptical about jukebox musicals (that mold a show from songwriters songbook or star selected song lists). Luckily for The Cher Show they have a terrific Book writer in Rick Elice (who wrote The Jersey Boys) and a compelling focus in Cher.
Cher is such a rich subject that the show engages three actresses to embody her, Micaela Diamond as The Babe; Teal Wicks as The Lady; Stephanie J. Block as The Star. The communicate with each other throughout the show providing insight and context throughout. Jarrod Spector is the perfect Sonny Bono, perfect in voice and well treated in retrospect.
It is not a transformational work but it is a VERY entertaining evening in the theater and sometimes that is all that is important.
