"The Very Thought of You" is a jazz-pop standard published in 1934, with music and lyrics by Ray Noble. In addition to Noble's own hit recording of the song with his orchestra, featuring the vocals of Al Bowlly, there was also a popular version recorded that same year by Bing Crosby. A decade later, the song was on the charts again in a version by Vaughn Monroe. Doris Day sang the song in the 1950 movie Young Man with a Horn, a fictional tale partly based on the life of early jazz trumpeter Bix Beiderbecke.

In 1961, "The Very Thought of You" was on the charts again, in a rhythm & blues version recorded by Little Willie John, and three years later a rock and roll version by Ricky Nelson reached #26 on the Billboard chart, lasting 7 weeks in the Hot 100 and crossing to #11 on Billboard's Easy Listening chart.

Ella Fitzgerald recorded this with Nelson Riddle on the 1962 Verve release "Ella Swings Gently with Nelson", and then again, live, on her 1974 Pablo release Ella in London, with Joe Pass on guitar.

Lyrics

I don't need your photograph to keep by my bed
Your picture is always in my head
I don't need your portrait, dear, to bring you to mind
For sleeping or waking, dear, I find

The very thought of you and I forget to do
The little ordinary things that everyone ought to do
I'm living in a kind of daydream
I'm happy as a king
And foolish though it may seem
Why to me that's everything

The mere idea of you, the longing here for you
You'll never know how slow the moments go till I'm near to you
I see your face in every flower
Your eyes in stars above
It's just the thought of you
The very thought of you, my love

I see your face in every flower
Your eyes in stars above
It's just the thought of you
The very thought of you, my love
