Beloved Australian guitarist Tommy Emmanuel recently released an album, Heart Songs, with fellow classic guitar player John Knowles. It's a mixed-bag of covers, including "Somewhere" from West Side Story, and originals. The pair joined us in the Paste Studio a few days after the album's release to play four highlights: Tanya Tucker's "San Antonio Stroll," The Bee Gees' "How Deep Is Your Love," Ray Charles' "I Can't Stop Loving You" and Billy Joel's "Lullabye (Goodnight, My Angel)."
