The people of Saipan sing many of the same church songs we do on Guam. And they have their own songs which we don't sing, since they started to have their own priests, separate from Guam, in 1899. Some of their songs were brought over by the German Capuchins who worked there from 1907 till 1919.
And they play the ukulele a whole lot more in Saipan than on Guam. More of an island flavor.
