There's a ton of stuff like this on youtube, from members of a Brazilian evangelical church Congregação Cristã no Brasil. I don't know if every male member plays an instrument, but a lot of them do, and it's part of the service - great big wind orchestras on their hymns. I don't think the accordion gets in on that, but of course the tuba does, and they also have an unusual fondness for gigantic contrabass saxophones, which are manufactured for them in Brazil. Female members are allowed to play organ, if I remember right. While the sax basses tend towards gigantism, the tubas run a little to dwarfism - I exaggerate, but they seem to like Eb bass tubas, and in small groups like this they'll play those florid improvised bass lines. One of the few stars of this world is a blind tuba player, Marcelo Cego (Blind Marcelo.)
