Elvis' single release of this song was recorded live on stage at the International Hotel in Las Vegas on February 18, 1970. It was originally written by Baker Knight for Perry Como, however, it was Ray Peterson who ended up recording it in 1959.
On stage with Elvis were: James Burton (lead guitar), John Wilkinson (rhythm guitar), Jerry Scheff (bass), Bob Lanning (drums), and Glen D. Hardin (piano). Hardin wrote the arrangement used. Bobby Morris and his orchestra accompanied the band. Charlie Hodge, The Sweet Inspirations and The Imperials provided vocal backup, with soprano vocal by Millie Kirkham added later.
"The Wonder of You" was paired with "Mama Like The Roses" as the B-side and shipped on April 20, 1970. "The Wonder of You" peaked at #9 in its 12-week run on the Billboard pop singles chart and peaked at #37 in its 10-week run on the country chart. It peaked at #1 for 6 weeks in its 20-week run on the British pop singles chart.
For technical reasons in the 2002 re-mastering for ELV1S 30 #1 HITS an alternate recording of the song in that same February 1970 engagement was chosen.
Others who recorded the song include The Platters, The Delltones, Duke Ellington, and The Sandpipers.
