"Have I Told You Lately That I Love You?" is a popular song written by Scotty Wiseman and published in 1945. It was the greatest hit of Wiseman and his wife and one of the first country music songs to attract major attention in the pop music field. It's repeating fourth line is "Well darling, I'm telling you now."
Bing Crosby and The Andrews Sisters recorded the song on November 25, 1949 and it had a good reception from the trade magazine Billboard who said: "Ditty’s a sprightly mountain-musiker that had its innings a couple of years back on straight hillbilly diskings. Bing and the gals are in top form as they harmonize it to a spanking fare-thee-well." The record entered the Billboard charts on January 21, 1950 and in a four-week stay it peaked at No. 24.
The earliest and easily most prominent recording of "Have I Told You Lately That I Love You" in the early rock era was by Elvis Presley. According to the book of the CD-boxset "Elvis - The Complete 50's Masters", Presley recorded it on January 19, 1957, at RCA's Radio Recorders in Hollywood for his Loving You album. Session musicians for the song included Presley himself on rhythm guitar, his usual lead guitarist Scotty Moore, with Bill Black on bass, D.J. Fontana on drums, piano by Dudley Brooks, organ by Hoyt Hawkins, and background vocals were of course The Jordanaires. When the song was included on the Loving You album release in July 1957, it immediately prompted both Ricky Nelson and Eddie Cochran to record cover versions of the song. Nelson's was the "B" side of a hit single ("Be-Bop Baby", released in September), while Cochran's was an album cut (released in November). The impact of the Elvis version was felt across the Atlantic.
