Schwartz is known for his lengthy and detailed on-air stories about his interactions with famous people, most often Frank Sinatra. He also claims an encyclopedic knowledge of Sinatra, and claims that Sinatra himself was amazed by Schwartz's knowledge of every song he had ever recorded. He champions young artists who carry on the traditions of the American Songbook, as well as loquaciously reveling in the songwriters and performers of the Sinatra era. In 1986 Schwartz won a Grammy Award for Best Album Notes for "The Voice - The Columbia Years 1943-1952".
