"You'll Never Know", sometimes referred to as "You'll Never Know (Just How Much I Love You)" in later years, is a popular song with music written by Harry Warren and the lyrics by Mack Gordon. The song is based on a poem written by a young Oklahoma war bride named Dorothy Fern Norris.

The song was introduced in the 1943 movie Hello, Frisco, Hello where it was sung by Alice Faye. The song won the 1943 Academy Award for Best Original Song, one of nine nominated songs that year. It was also performed by Faye in the 1944 film Four Jills in a Jeep.

The song is often credited as Faye's signature song. However, Faye never released a record of the ballad, and frequent later recordings of the song by other singers diminished her association with it.

Renée Fleming recorded a version of "You'll Never Know" for the film The Shape of Water.

Dame Vera Lynn, DBE (born Vera Margaret Welch on 20 March 1917), widely known as "The Forces' Sweetheart" is an English singer, songwriter and actress whose musical recordings and performances were enormously popular during the Second World War. During the war she toured Egypt, India and Burma, giving outdoor concerts for the troops. The songs most associated with her are "We'll Meet Again", "The White Cliffs of Dover", "A Nightingale Sang in Berkeley Square" and "There'll Always Be an England".

She remained popular after the war, appearing on radio and television in the UK and the United States and recording such hits as "Auf Wiederseh'n Sweetheart" and her UK Number one single "My Son, My Son".

In 2009 she became the oldest living artist to make it to No. 1 on the British album chart, at the age of 92. She has devoted much time and energy to charity work connected with ex-servicemen, disabled children and breast cancer. She is still held in great affection by veterans of the Second World War and in 2000 was named the Briton who best exemplified the spirit of the twentieth century.

In September 2009 Lynn became the oldest living artist to make it into No. 1 in the British album chart, at the age of 92, passing such veterans of music as American jazz trumpeter Louis Armstrong and French singer Charles Aznavour. Her collection We'll Meet Again: The Very Best of Vera Lynn entered the chart at number 20 on 30 August, and then climbed to number 2 the following week, before reaching the top position, outselling both the Arctic Monkeys and the Beatles.[46] In its third week the album went gold with sales of over 100,000.

On 20 March 2014, her 97th birthday, Lynn announced that she was releasing a new album Vera Lynn: National Treasure – The Ultimate Collection. The album was released on 2 June, to mark the 70th anniversary of the D-Day landings, which occurred four days later.

In August 2014, Lynn was one of 200 public figures who were signatories to a letter to The Guardian opposing Scottish independence in the run-up to September's referendum on that issue.

You'll never know just how much I miss you
You'll never know just how much I care
And if I tried, I still couldn't hide my love for you
You ought to know, for haven't I told you so
A million or more times?

You went away and my heart went with you
I speak your name in my every prayer
If there is some other way to prove that I love you
I swear I don't know how

You'll never know if you don't know now
(You went away and my heart went with you
I speak your name in my every prayer)
If there is some other way to prove that I love you
I swear I don't know how

You'll never know if you don't know now
You'll never know if you don't know now
