American composer Robert Allen (1927–2000) was a prominent figure in mid-20th century popular music, known for co-writing numerous hit songs. His collaborations with lyricist Al Stillman produced enduring classics like "Chances Are," "It's Not For Me To Say," and "Come Fly With Me," which became signature tunes for artists such as Johnny Mathis and Frank Sinatra. Allen's melodic sensibility and sophisticated arrangements contributed significantly to the Great American Songbook.
