I am part of a male choir and there are a number of songs that I could suggest, but I'm not sure that you would know them. Reason being, I don't know the names of the artist. I do suggest, however, to start with songs written for male groups, i.e. Canton Spirituals, Men of Standard, Wille Neal Johnson and the Gospel Keynotes are to name a few. I suggest them, because a number of songs written by theses artist are easy to learn. I hope that this suggestion helps, even a little.
