From the wiki: “‘Let Your Love Flow’ was written by Larry E. Williams, a former roadie for Neil Diamond and was offered to Diamond first, but he turned it down. The song was first recorded by Gene Cotton (on his 1975 album For All The Young Writers and released as the B-side to ‘Keepin’ It On The Road’).
“In 1976, the song became a crossover hit in the United States for The Bellamy Brothers, reaching #1 on the 1976 Billboard Hot 100, #2 on Hot Adult Contemporary Tracks, and #21 on Hot Country Singles. The Bellamy Brothers’ recording also became a sizable international hit.”
