The Herald can reveal that the Green Tea comic will feature a sketch about the Kerry GAA player in his next live show.
Although there's clearly no love lost between himself and the sports-star in the wake of their recent high profile scuffle, Callan has not backed down from continuing to poke fun at fashion-forward Galvin.
He'll take to the stage at the Olympia Theatre with his Live And Uncut show on January 12 -- and is promising attendees a memorable performance.
"We've a great team of writers who are ready to transfer the mayhem and energy of the show from the radio to the stage, with an evening of sketches and as many characters as we can physically fit in," he said.
He has confirmed that the show, his first one at the Olympia in three years, will include all his most memorable characters from over the years -- including a skit about Galvin.
Last month saw the pair involved in an incident in Kehoe's pub on South Anne Street which led to the gardai being called. It was later described by an eye witness as "handbags at 20 paces" after the confrontation between Mr Galvin, the comic and his associate James McDonald.
It was alleged that Galvin was upset over a sketch on the satirical show which made humorous references to him and television presenter Grainne Seoige. The sports star had told friends that he was "excruciatingly embarrassed" about some of the skits and subsequently squared up to the comedian about it.
But Callan's legal team recently sent a letter to gardai confirming that he does not want to press charges. The Monaghan-born comic recently came out on the Saturday Night Show as he denied claims that he was homophobic.
"Let's get the record straight," he said. "I'm not a homophobe, because I'm gay. Big deal.
"You're gay, just get on with it. It was obviously something you have to acknowledge publicly to help the whole process along. I suppose I have been out for years with my best friends. It's something I didn't feel I had to make a big issue of it and announce it, but there is unnecessary stuff I felt I had to get rid of and put to bed."
