There is no known Composer because it is an African Folk song.
The genre of the piece is a folk song. The reasoning behind the song is because the Africans wanted to be free from slavery. The words are saying that they are going on the "freedom Train" to South Africa. This song is very dear to Africans that were in slaved or imprisoned because this song gave them a symbol of hope for the future. This song was also passed down from generations to become a form of what we are singing today.
P.S Please never ever have us use adobe spark again. i had a lot of trouble doing this because it is very buggy. Also, It does not have slides so i couldn't really put slides in and finding pictures is very difficult because you can not go to google to find one.
