My name is Mary Giran

I would like to know if any one can sing any inspirational song by Thoro Harris?
I have a songbook, the cover page published by E.A.K. Hackett.
Gospel Quintet Songs, published by Thoro Harris.
I cannot seem to find too much about Thoro Harris and his music.
Please let me know if the cover page goes to the gospel quintet songs.

Thank you
