"You Don't Know Me" was written by Cindy Walker and Eddy Arnold in 1955 and recorded by Arnold that year.
The first version of the song to make the Billboard charts was by Jerry Vale in 1956, peaking at #14 on the pop chart. Arnold's version followed two months later and went to #10 on the country chart. Cash Box magazine, which combined all best-selling versions at one position, included a version by Carmen McRae that never appeared in the Billboard Top 100 Sides listing.
The song has been performed or recorded by hundreds of artists, including Ray Charles, Elvis Presley, Bob Dylan, and Willie Nelson. Charles re-recorded the song with Diana Krall on his album of duets, Genius Loves Company and it was sung by Meryl Streep in the 1990 movie Postcards from the Edge, and by John Legend in an episode of Curb Your Enthusiasm. Robert Downey Jr also performs this song as Blake Allen in the James Toback movie Two Girls and a Guy.
