From the wiki: “‘Melody of Love’ was originally written by Hans Engelmann in 1903, with lyrics added in 1954 by Tom Glazer (‘On Top of Spaghetti‘). An instrumental version recorded by Billy Vaughn was the highest-charting version on the Billboard charts in 1955. Other charting versions in 1955 were by David Carroll, The Four Aces, Frank Sinatra, and, in the UK, The Ink Spots. Vaughn’s recording first reached the Billboard Best Seller chart on December 1, 1954 and it lasted 27 weeks on the chart, peaking at #2.
“In the United Kingdom, a version by the Ink Spots was the sole hit version, charting at #10. A Jim Reeves spoken-word recording, posthumously released, brought the song the country charts in 1970 titled ‘Why Do I Love You (Melody Of Love)’ as the B-side to the Top 10 Country single, ‘Nobody’s Food’.”
