Brock Speer (December 28, 1920 – March 29, 1999) sang bass for the Speer Family Southern Gospel musical group and was a leader in Southern Gospel music.
One might say that Southern Gospel music was Speer's life.
David Liverett's book, This Is My Story: 145 of the World's Greatest Gospel Singers, includes the following comments written by Speer's nephew, Steve Speer, and printed in the program distributed at Brock's funeral: Jackson Brock Speer was born in Winston County, Alabama, just two months before his father and mother began a singing group called the Speer Quartet.
For the remaining seventy-eight years of his life, he was inextricably intertwined with that group.
With only one exception -- World War II -- he sang with his family his entire life.
