Being a lover of British TV sitcoms, Glenn has directed versions of Black Adder, Fawlty Towers and 'Allo 'Allo in Whanganui, which meant directing Last of the Summer Wine would be a loved project - even though the five-week rehearsal was very skimpy.
The plot involves three male senior citizens unencumbered by wives, jobs or any other responsibilities, who have never really grown up.
They explore their world in the Yorkshire Dales and spend their days speculating about their fellow townsfolk and thinking up adventures not usually favoured by the elderly.
Glenn said it was tough at first working with actors who weren't hugely experienced.
"But I got very lucky with the calibre of people who auditioned, thank goodness."
When Glenn arrived in the Hawke's Bay four years ago he auditioned and was cast in a production of Last of the Summer Wine.
"I didn't even know there was a play. I loved it so was determined to do it as a Whanganui production."
There have been trials and tribulations through the short rehearsal period, he said.
"But I can honestly say we're ready - maybe because of the pressure we've been under."
There was a gala opening on Friday night and performances are at the Repertory Theatre in Ridgway Street from Saturday, July 29, at 7.30pm, a matinee on Sunday, July 30, at 2pm, then Thursday to Saturday, August 3-5 at 7.30pm.
After having a breather, Glenn is hoping to return to teaching drama in schools again.
"I used to teach at Nga Tawa and I enjoy working with young people - they are very creative."
