Wiseman says the three actors had performed together in other shows and their talents worked well together.
"They are all very funny, have great voices and musical talents and we thought they could put together a great musical comedy."
The little dog in the photo belongs to Lennox and is not part of the show.
"The dog doesn't travel," says Wiseman.
"It might be trained up at a later stage but for now, it's in the photo just because it wanted to be there."
At Home with Leo, Clever & Constance is an adults-only evening of hilarious musical mash-ups, where popular songs from the past will be given an irreverent makeover, alongside a few racy ukulele originals.
Audience reactions have ranged from "The best night, haven't laughed so much in years" to "How could you do that to such a beautiful song?"
The show is hosted by Metropolitan Club, purveyors of vintage and heritage happenings.
At Home with Leo, Clever & Constance: Whanganui Musicians Club, 65 Drews Ave, Saturday, December 8, at 8pm. BYO dinner and drinks. Tickets $20. Book at eventfinda or pay at the door.
