Husband and wife Mike Palter and Lynn Jackson have been performing as a jazz and cabaret duo for 46 years.

And they like nothing better than sharing their love of the music from the Great American Songbook, a collection of popular songs and jazz standards from the early 20th century, with young people.

“Many of them haven’t heard jazz before,’’ Palter said. “But when they do, they love it.’’

Twelve years ago, the Manchester-by-the-Sea couple started a program called Jazz is a Rainbow in Lynn — Palter’s hometown — geared to underserved kids. The program then moved to Providence, where it is ongoing.

This year, Jazz is a Rainbow is back locally, with performances at LynnArts 7 p.m. Friday, Aug. 26, and Saturday, Aug. 27.

Each show, which Palter describes as a “musical theatrical performance,’’ features a script written by Palter on various themes. The show at LynnArts is “Jazz is a Rainbow: The Harlem Strut.’’

“It’s a celebration of those remarkable musicians, singers, poets, and writers whose contributions to the Harlem Renaissance continue to influence America,’’ Palter said.

He said one important aspect of the show is that “jazz was the first opportunity after the Civil War for blacks and whites to be able to work together. The kids aren’t aware of that until they get with us.

“The play very much deals with race and is being presented in a city where race is an enormous question, and at a time of very grave national concerns about race,’’ Palter said.

He describes Jazz is a Rainbow as a camp for local kids, ages 10 to 19, who don’t have performing experience. Participation is free.

“Musical theater is a new skill for them,’’ Palter said. “It’s an ensemble, which is also a new experience. And, they have enormous fun.’’

Many have gone on to pursue theater and performance, he said, adding that Alex Newell of Lynn, who appeared in the television series “Glee,’’ is a former cast member.

Palter, who plays standup base, and Jackson, who plays piano, rehearse with the cast and play for the performances, as do other professional musicians. All performances are free.

“‘Jazz is a Rainbow has become a symbol of a way forward,’’ Palter said. “It brings communities together and has changed lives. That sounds pompous, but it’s true.’’
