Roy Rogers (born Leonard Franklin Slye November 5, 1911 - July 6, 1998) was an American singer and cowboy actor who was one of the most popular Western stars of his era. Known as the "King of the Cowboys", he appeared in over 100 films and numerous radio and television episodes of The Roy Rogers Show. In many of his films and television episodes, he appeared with his wife Dale Evans, his golden palomino Trigger, and his German Shepherd dog Bullet. His show ran on radio for nine years before moving to television from 1951 through 1957. His productions usually featured a sidekick, often Pat Brady, Andy Devine, or George "Gabby" Hayes. In his later years, Rogers lent his name to the Roy Rogers Restaurants franchised chain.
The Roy Rogers Show radio program began in 1944, ended in 1955, and was carried on more than 500 stations. Like the television program of the same name, the show centered on Roy Rogers. Initially, the radio show differed in format from The Roy Rogers Show on TV, with the radio version being more oriented toward music. Toward its end, however, it moved more toward the adventure featured in the TV show.
The main actors in the program were familiar to fans of Rogers' movies. He was the star, with wife Dale Evans and sidekick Gabby Hayes. Initially, the Sons of the Pioneers were the featured musical group; in 1948, they were replaced by Foy Willing and the Riders of the Purple Sage. In the show's later years, Pat Brady replaced Hayes. Hayes was Rogers' "grizzled sidekick from the movies," whereas Brady "was a different sort of sidekick, younger and more useful, although still comical."
Other people heard in the program over the years included Forrest Lewis, The Whippoorwills, and Joseph Kearns. Rogers' horse, Trigger, and dog, Bullet, were also featured regularly in the program. (Source: wikipedia.org)
