Denver's next album, "Poems, Prayers & Promises" (1971), was a breakthrough for him in the U.S., thanks in part to the single "Take Me Home, Country Roads", which went to No. 2 on the "Billboard" charts despite the first pressings of the track being distorted. Its success was due in part to the efforts of his new manager, future Hollywood producer Jerry Weintraub, who signed Denver in 1970. Weintraub insisted on a reissue of the track and began a radio airplay campaign that started in Denver, Colorado. Denver's career flourished thereafter, and he had a series of hits over the next four years. In 1972, he scored his first Top Ten album with "Rocky Mountain High", with its title track reaching the Top Ten in 1973. In 1974 and 1975, Denver experienced an impressive chart dominance, with a string of four No. 1 songs ("Sunshine on My Shoulders", "Annie's Song", "Thank God I'm a Country Boy", and "I'm Sorry") and three No. 1 albums ("John Denver's Greatest Hits", "Back Home Again", and "Windsong").
