"Okie From Muskogee," "The Fightin' Side of Me," and "I Wonder If They Think of Me" (Haggard's 1973 song about an American POW in Vietnam) were hailed as anthems of the Silent Majority and have been recognized as part of a recurring patriotic trend in American country music that also includes Charlie Daniels' "In America" and Lee Greenwood's "God Bless the USA." Although Gordon Friesen of "Broadside" magazine criticized Haggard for his " Birch-type songs against war dissenters," Haggard was popular with college students in the early 1970s, not only because of the ironic use of his songs by counterculture members, but also because his music was recognized as coming from an early country-folk tradition. Both "Okie from Muskogee" and "The Fightin' Side of Me" received extensive airplay on underground radio stations, and "Okie" was performed in concert by protest singers Arlo Guthrie and Phil Ochs.
