Montgomery High School drama teacher Sue Byrne is justly famous in Santa Rosa for the ferocious enthusiasm she brings to every project.

But she’s especially excited about the current Montgomery production of “The Imaginary Invalid,” Moliere’s 17th-century French farce about hypochondria, now updated to the 1960s.

“Last year, I took my drama production students up to see several plays at the Oregon Shakespeare Festival in Ashland,” Byrne said.

“The students fell in love with their production of ‘The Imaginary Invalid,’ and wanted so badly to do it at Montgomery,” she said.

“So, last fall, I contacted the festival and asked for permission to do this adaptation by Oded Gross and Tracy Young, with music and lyrics written by Paul Prendergast,” Byrne said. “We were given the green light and were put directly in touch with the people who created it.”

As a result, the high school ultimately opened the show April 19 to very warm response. The closing performances are at 7 p.m. Wednesday through Friday, April 25-27, in the Performing Arts Center at Montgomery High School, 1250 Hahman Drive, Santa Rosa.

Ever persuasive, Byrne points out the cost of seeing the show here is much more reasonable than a trip to Oregon.

Admission costs $10 for adults; $8 for students. Tickets will be sold at the door.
