Some context: Petra is a music group regarded as a pioneer of the Christian rock and contemporary Christian music genres. Formed in 1972, the band took its name from the Greek word for "rock". Though it disbanded formally in 2006, incarnations have played reunion shows in the years since and released an album in November 2010. In 2013, it reformed with a new drummer, Cristian Borneo, and recorded a new song titled "Holy is Your Name", before going back on tour.
In 1976, Glover had resigned from the band. He was replaced by a string of drummers which included a childhood friend of Hough, Bob Rickman, and Glover's cousin, Mark Richards. However, by the time their record deal for the second album went through, Richards had already left, and Petra decided to hire Glover as a studio musician.  By Hartman's admission, his vocal style did not match well with the band's genre, and Petra brought in a number of guest vocalists for the second record, among them former e vocalist Greg X. Volz (that band's name being a lower-case abbreviation of "Emmanuel"). Volz took the lead vocals on two songs and backed up several others. Among Volz's songs was a cover of the Argent anthem "God Gave Rock and Roll to You," which Myrrh had hoped to release as a radio single to the secular market. The song was immediately controversial - and revolutionary. "It was the boldest statement anyone in Christian music had made until that time," said Ambassador Artist Agency president Wes Yoder. "This was a radical notion, especially in the minds of the leaders of conservative churches." Other guest singers featured in the album were Steve Camp, Karen Morrison, and Austin Roberts.  The recording process also was marked by disputes: the label refused Hartman's request to name the album God Gave Rock and Roll to You while a bluesy, crowd-favorite track written by Hartman about rejecting the pre-Christian self, "Killing My Old Man," was deemed too controversial and cut from the album (the song would later appear on the album Never Say Die). With a harder-edged sound reminiscent of Led Zeppelin and Deep Purple, Come and Join Us was released in 1977. It failed to sell well, however, and Myrrh dropped Petra from its label.

Some context: William Frederick "Buffalo Bill" Cody (February 26, 1846 - January 10, 1917) was an American scout, bison hunter, and showman. He was born in Le Claire, Iowa Territory (now the U.S. state of Iowa), but he lived for several years in his father's hometown in Toronto Township, Ontario, Canada, before the family returned to the Midwest and settled in the Kansas Territory. Buffalo Bill started working at the age of eleven, after his father's death, and became a rider for the Pony Express at age 14. During the American Civil War, he served the Union from 1863 to the end of the war in 1865.
After his mother recovered, Cody wanted to enlist as a soldier in the Union Army during the American Civil War, but was refused because of his young age. He began working with a freight caravan that delivered supplies to Fort Laramie, in present-day Wyoming. In 1863, at age 17, he enlisted as a teamster with the rank of private in Company H, 7th Kansas Cavalry, and served until discharged in 1865.  The next year, Cody married Louisa Frederici. They had four children. Two died young, while the family was living in Rochester, New York. They and a third child are buried in Mount Hope Cemetery, in Rochester.  Cody went back to work for the Army in 1868 and was Chief of Scouts for the Third Cavalry during the Plains Wars. Part of the time, he scouted for Indians and fought in 16 battles; at other times, he hunted and killed bison to supply the Army and the Kansas Pacific Railroad. In January 1872, Cody was a scout for the highly publicized hunting expedition of the Grand Duke Alexei Alexandrovich of Russia.  Cody was awarded the Medal of Honor in 1872 for gallantry as an Army scout in the Indian Wars. It was revoked in 1913, along with medals of many other recipients, when Congress decided to create a hierarchy of military awards to replace the patchwork which had evolved over time. The result was that the Medal of Honor became the highest military decoration, with its award restricted to "officers or enlisted" personnel who demonstrated bravery "above and beyond the call of duty." The law also allowed the government to retroactively change the honor rolls, resulting in civilian scouts who met neither criterion having their awards rescinded. Cody was one of five scouts affected, whose medals were stripped shortly after Cody died in 1917.  Cody's relatives objected, and over a number of years they wrote repeatedly to Congress seeking reconsideration. All efforts failed, including a 1988 letter to the US Senate from Cody's grandson. A year later the office of Senator Alan K. Simpson of Wyoming took up the cause. Its brief, which argued for the retroactive elevation of these civilian scouts' status to meet the Medal's standards, persuaded the Army Board for Correction of Military Records to restore their medals. To this day, they are the only honorees who were civilians at the time of their award to regain the Medal of Honor.
