Hugh Jackman and Kate Hudson on the musical alchemy of “Song Sung Blue”

In their new movie, “Song Sung Blue,” Hugh Jackman and Kate Hudson play Mike and Claire Sardina, the real-life musical impersonators who sang as Neil Diamond and Patsy Cline. Jackman reveals to Tracy Smith how he “discovered” his co-star (watching her sing on “CBS Sunday Morning”!) and their shared chemistry, while Hudson talks about playing a less glamorous role.
