If You Love Me (Let Me Know)

"If You Love Me " is a song written by John Rostill that was a 1974 hit single for Olivia Newton-John. It was her second release to hit the top 10 in the United States, reaching number 5 on the pop chart and number 2 on the Easy Listening chart. It also reached number 2 on the Billboard country chart. As with her single "Let Me Be There", Mike Sammes sings a bass harmony. It was nominated for the 1974 Country Music Association Award for Single of the Year.
Record World said that "Another John Rostill tune produced in the style of 'Let Me Be There' should guarantee a similar kind of success saga for her follow-up."
