Diversional therapist Tina Wright invited the group to entertain the residents and between the costumed performances, Shepherd delivered a few dance lessons.
To the accompaniment of favourite tunes like Walking My Baby Back Home, she led the audience in some toe-tapping and hand movements they could enjoy from the comfort of their armchairs.
"I had a similar group in Auckland that I ran for 10 years," said Shepherd.
"I started the Whanganui group two years ago and none of these women had ever put on a tap shoe before that."
The group meet up for social outings between rehearsals and have become a "sisterhood".
Shepherd said she started tap dancing as a 9-year-old and after taking a break for a few of her adult years, she returned with a vengeance.
"I completed a few postgraduate qualifications and now I really enjoy teaching others."
She feels very proud of her group, she says, and how they have proven that age is no barrier to learning something new.
