More Than You Know is a popular song, composed by Vincent Youmans with lyrics by Billy Rose and Edward Eliscu. The song was published in 1929. The song was introduced in the Broadway musical Great Day where it was sung by Mayo Methot. It was also popularized on the stage and radio by Jane Froman.The song was subsequently featured in three musical films: Hit the Deck (1955), sung by Tony Martin; Funny Lady (1975), sung by Barbra Streisand (who first recorded it for her 1967 studio album, Simply Streisand); and The Fabulous Baker Boys (1989) sung by Michelle Pfeiffer. It has been recorded by many artists. This version features a root-based chord-blocking technique we have used in a number of our arrangements. It's not too hard and sounds great!
