Pat Boone
A favorite musical artist of Lois Lane, Pat Boone records a song with her about Superman ("Come Sing a Song of Superman")--written by Clark Kent. Superman later realizes that the song he wrote in a dream has the first letter of each stanza's lyrics combining to spell out his secret identity. He uses various ingenious methods to make sure that no broadcast versions of the song are ever heard (SGLL No. 9/3, May 1959: "Superman's Mystery Song!").
