From the wiki: “‘Words of Love’ was written by Buddy Holly and recorded by him on April 8, 1957. Holly sang all the harmonies, with producer Norman Petty double-tracking each part and combining them. The song was not a notable hit for Holly, although it is regarded as one of his most important recordings.
“The cover version by The Diamonds, released in May 1957, reached #13 on the Billboard Hot 100 in July. ‘Words of Love’ was also covered by The Beatles on the album Beatles for Sale. John Lennon and Paul McCartney were big Buddy Holly fans; it would be his songs that inspired them to become songwriters. The Beatles’ association with ‘Words of Love’ dates back to the groups’ earliest days playing The Cavern in 1961 and 1962.”
