In terms of sheer vivacity, it’s easy to understand this work’s appeal: It’s packed with the kind of raucous song and rambunctious dance that are frequently in short supply in today’s committee-approved musical climate.  … This all makes for the most energetically entertaining show at NYMF this year. (Matthew Murray, talkinbroadway.com)

A foot-stomping, Bible-pounding, down-home country musical set in the back hills of Kentucky, Sherry Landrum and George S. Clinton's That Other Woman's Child features a delightful score of bluegrass dance tunes and country-western ballads, anthems, and hymns. With choreography by Mark Knowles and musical direction by David Libby, the show's musical numbers are terrifically entertaining. (Lisa Jo Sagolla, Backstage)

Wow, did I ever love seeing the bluegrass musical That Other Woman’s Child. (Dr. Joy Browne, syndicated radio)

In a period when the American culture is in political turmoil and society is searchdng for both, a sense of understanding, and a sense of humor, That Other Woman’s Child turns us back to our American heritage. Liberating us with hearty laughs, southern charm, and bluegrass music, Sherry Landrum and George S. Clinton have crafted a satirical modern musical comedy that pokes fun at the traditional structures, while rooting us in the values of home and family. (Jennifer Rathbone, Theatre Online.com)
