If You Love Me, Let Me Know is the third North American album by singer Olivia Newton-John, released on 28 May 1974. Other than the title track, all the material was from her previous three international albums, Olivia (1972), Music Makes My Day (1973) and Long Live Love (1974). It was her first album to top the Billboard 200.
Two hit singles were released from the album, the title song and "I Honestly Love You", the latter of which became Newton-John's first number-one US single, and her signature song as well.
Background
Six of the tracks on the album are from her European and Australian release, Long Live Love, two are tracks from Olivia and one from Music Makes My Day, with the title song being the only new addition.
It was the first of two Newton-John albums to top the Billboard 200 pop albums chart,[3] the second being Have You Never Been Mellow the following year. Two hit singles were culled from the LP in the US: the title song (No. 5) and "I Honestly Love You", which became Newton-John's first number-one single in the US after listener requests for the song prompted MCA to release it as a single, much to Newton-John's delight after she originally pleaded with the label to release it as such.[3] Both songs reached the top 10 of the US Pop, Adult Contemporary and Country charts,[3] affirming Newton-John's status as the top female country-crossover star of the day and continuing the chart hot streak begun with the Grammy-winning "Let Me Be There" the previous year.
The title track ranks as Newton-John's highest-charting single on the country charts, reaching No. 2,[3] although she would have more top 10 hits.
