Several casting changes have taken place at the Old Lyric Repertory Company in Logan, according to executive producer Sid Perkes. Changes affect all four summer productions.

Marsha Miller, guest actress for the summer, has resigned for medical reasons, Perkes announced. Miller, a member of Actor's Equity Association, had been cast in all Lyric productions."We are sorry to see Marsha leave the company but understand that health considerations are of foremost importance," Perkes said.

"We are encouraged that she will be able to resume her career this fall."

Callie Kennedy replaces Miller in "The Foreigner" and "Pump Boys and Dinettes," and Molly Cameron will ssume Miller's roles in "Da" and "You Never Can Tell."

Kennedy is a first time member of the Lyric company, coordinating the newly created high school apprentice program and is slated to appear later in the season in` `Da." She is a graduate of Loretto Heights College in Colorado, where she appeared in numerous musicals. Last fall she participated in a USO tour to the Far East.

Kennedy is now appearing as Catherine Simms in "The Foreigner" and Rhetta Cupp in "Pump Boys and Dinettes."

Cameron is a veteran Lyric actress and was a guest artist last season, appearing in "Noises Off," "The Contrast" and as Eleanor in "The Lion in Winter."

She is now a resident of New York City and appeared in "The Summer Face Woman" at the La Mama Theatre. She also appeared in the world premiere of "In the Voodoo Parlor of Marie Laveau" at the Studio Ensemble Theatre in Los Angeles.

At the Lyric, Cameron will appear as the mother in "Da" and Gloria in "You Never Can Tell." She is a member of Actor's Equity Association.
