When I'm Thinking of You is an album by American singer Tommy Sands. It was arranged by Nelson Riddle and released in 1959. In his biography of Riddle, September in the Rain, Peter J. Levinson wrote that Riddle's arrangements for Sands were "as original and as stimulating as he wrote for any singer, and obviously Sands was musically comfortable with him". Sands subsequently described Riddle as the "best arranger I ever worked with".
