 Climb up on my knee, Sonny BoyThough you're only three, Sonny BoyYou've no way of knowingThere's no way of showingWhat you mean to me, Sonny Boy.
 When there are grey skies,I don't mind the grey skies.You make them blue, Sonny Boy.Friends may forsake me.Let them all forsake me.I still have you, Sonny Boy.
 You're sent from heavenAnd I know your worth.You made a heaven For me here on earth.
 When I'm old and grey, dearPromise you won't stray, dearFor I love you so, Sonny Boy.
 When there are grey skies,I don't mind grey skies.You make them blue, Sonny Boy.Friends may forsake me.Let them all forsake me.I still have you, Sonny Boy.
 You're sent from heavenAnd I know your worth. You've made a heavenFor me here on earth.
 And the angels grew lonelyTook you because they were lonelyI'm lonely too, Sonny Boy.

 Singer Eddie Fisher was always called "Sonny Boy" by his family because of the popularity of this song, which was recorded the same year as Fisher's birth. In his autobiography, Fisher wrote that even after he was married to Elizabeth Taylor in 1959, earning $40,000 a week performing in Las Vegas, spending time with Frank Sinatra and Rocky Marciano, and had songs at the top of the charts, his family still called him "Sonny Boy".

 According to 1986 British TV documentary "The Real Al Jolson Story," "Sonny Boy" was written in a single sitting in a hotel room in Atlantic City as a joke. In the 1956 DeSylva, Brown, and Henderson biopic "The Best Things in Life Are Free", the songwriting trio are tired of being pestered by Al Jolson. They decide to write a song so unabashedly maudlin that even Jolson would hate it, and leave them alone. True to style, Jolson did not hate the overt sentimentality of the song and it became one of the biggest popular hits of the early 20th century.
 Various renditions of the song are used as a leitmotif in the 1990 psychological horror film Jacob's Ladder, indicating protagonist Jacob's love for his late son Gabe. The film notably omits the last verse, which relates the narrator's loss in kind, perhaps as an artistic choice.
 The song title is the title of a Dutch book and movie about a Surinamese/Dutch family and their lives leading up to and in the second World War. The little boy's nickname is Sonny Boy after this song, which was popular when he was born.
 The song was referenced by the British band Black Midi in their song "John L" with the lyric "Three encores of 'Oh Sonny Boy' [sic] backed only by accordion". The reference is a nod to the blackface minstrelsy performed by Jolson, as the song's protagonist is a fascistic cult leader and espoused racist.
