From the wiki: “‘Mountain of Love’ was written by Harold Dorman who first recorded the song in 1959, releasing it as a single in 1960 that peaked in the Top 40 at #21.
“In 1960, UK singer Kenny Lynch covered ‘Mountain of Love’ for the UK market, becoming his first charting single on the UK Singles chart. (Trivia: Lynch was on the same bill as the Beatles for their first UK tour, with the top-billed Helen Shapiro, in early 1963, and made the acquaintance of John Lennon and Paul McCartney. Later that year, he would become the first singer to cover a Beatles song (‘Misery’). In 1973, Lynch would also be among the celebrities appearing on the album cover of Wings’ Band on the Run.)
“A Johnny Rivers 1964 cover recording went Top 10 in the US and Top 5 in Canada. Charlie Pride topped the US Country singles chart in 1981 with his cover of ‘Mountain of Love’, his 26th #1 country hit.”
