Hartford's recording of "Gentle on my Mind" attracted Glen Campbell's attention after he heard it on the radio and bought the single.[17] He felt the song is "an essay on life" and was "knocked out" by the scenery it describes.[18] At the time, Campbell worked as a studio musician with The Wrecking Crew; he rearranged the song and with the band, he recorded a demo at Capitol Studios.[19] Campbell left the demo tape at the studio for producer Al De Lory, who made slight production arrangements that Capitol Records accepted as a master for the single.[20] Campbell's cover of "Gentle on My Mind" was released with "Just Another Man" on the B-side in June 1967.[21] Upon its release, Billboard predicted the single would reach the Billboard Hot 100 chart.[22] It peaked at number 30 on the magazine's Hot Country Songs,[23] and at number 62 on the Hot 100.[24] The success of the song, which was originally intended for the country music market, helped Campbell cross over to the pop market.[25][26]
