I'm Gonna Sing! is the name of the programme to be performed by the Whanganui Schola Sacra Choir on Sunday.
The performance is under the banner of Musicians for the Sarjeant, a fundraising group for the gallery's redevelopment project.
The concert promises "a melodious miscellany of folk songs, spirituals, world music and classic favourites".
Directed by Richard Tankersley, the Schola Sacra Choir are a 40-strong choir of soprano, alto, tenor and bass (SATB) singers.
Their last concert was I Sing of Two Worlds with the Youth Choir and soloists at Christ Church on August 12.
They often lend their voices to supporting the Whanganui community, donating the proceeds from their concerts to local projects and causes.
