"The Voice Of Prophecy [http://www.vop.com/article/1005/listen/hms-richards-classic-broadcasts] is a long-running Seventh-day Adventist religious radio broadcast founded in 1929 by H.M.S. Richards, Sr. ... It was one of the first religious programs in the United States to broadcast nationally. ... Throughout the years Voice of Prophecy broadcasts were marked by an opening theme song of "Lift Up the Trumpet" performed by the King's Heralds quartet and closed with Richard's poem "Have Faith in God" each week having a new verse written. ... H.M.S. Richards, Sr. was speaker from 1929 to 1969. In 1969, Richards' son, H.M.S. Richards, Jr., succeeded him and was speaker from 1969 to 1992. ... Various musicians perform on the broadcast. Female vocalist Del Delker began as a regular on the program since 1947 and is regarded as one of the leading female singers of religious music. The male quartet King's Heralds also performed weekly on the program from 1936 until 1982." (http://en.wikipedia.org/wiki/Voice_of_Prophecy)
"The King's Heralds began in 1927 by four college students; brothers Lewis, Waldo and Wesley Crane and Ray Turner (1908-2008) in Keene, Texas who began singing gospel music, under the name Lone Star Four. They soon appeared with Pastor R. L. Benton on his radio program on KFPL from Waco, Texas. In 1936, they were invited by H.M.S. Richards to join the Voice of Prophecy in California, and were renamed the King's Heralds after a radio naming contest. This association continued until 1982, when they became a self-supporting ministry. The King's Heralds are also known by the name The Heralds, in Portuguese as the Arautos do Rei and in Spanish as Los Heraldos del Rey. Purported to be the oldest continuous gospel quartet in America, they have been singing for over 80 years. Throughout the years they have performed in over 50 countries and continue to tour extensively. They were the first gospel music group from the West to tour The People’s Republic of China since 1949, singing for the "First Invitational Symposium on the Christian Church in China" sponsored by the US/China Education Foundation. Long associated with the Seventh-day Adventist Voice of Prophecy radio broadcast, the Heralds are now promoted as trans-denominational and are regular guests on Praise The Lord on TBN and It Is Written."

"This is a classic 15-minute radio program featuring the Bible teachings of Amazing Facts founder Joe Crews." "The first Amazing Facts radio program went on the air in Baltimore in the spring of 1966," "In 1994, Joe Crews died suddenly after nearly 30 years as the ministry's director and speaker." Each broadcast "begins with an amazing scientific or historical fact and follows with a biblical message that will open your eyes to amazing Bible truth!" ~AF
