It is interesting that the Mormons had formed a brass band in the mid 1840s. On the trek west, their playing was one of the few ways to earn a bit of cash. Repertoire included marches, some folk songs and plenty of popular songs (I won't even attempt a list, that is easier found by consulting songbooks), often with new lyrics.
A great emphasis was placed on music and a large amount of pianos and organs were brought over, quite a feat before the railroad.
