I got to sing, appropriately, the gospel I'm Gonna Sing
in an SAB arrangement by Bettina Röttger and Stefan Kutter when a member of Das Trio
sometime in 2007. There are divisi in the upper voices making it into a quintet. As the bass singer, I loved leading off the fun. As with so many gospels, the lyrics are easy to learn just changing one word in each verse. To whit: "I'm gonna sing ..., preach ..., shout ..., pray ...," and finally "sing". All great stuff indeed!
The arrangement can be found in Chor aktuell junior
