It is always interesting to listen to different musicians playing same piece of music. The interpretation is different and the piece changes. I listened to some.
But reading the lyrics, this your interpretation put a huge smile on my face 
This is great. BIG like!!!

I found out that:
"In a Mellow Tone", also known as "In a Mellotone", is a 1939 jazz standard composed by Duke Ellington, with lyrics written by Milt Gabler. The song was based on the 1917 standard "Rose Room" by Art Hickman and Harry Williams, which Ellington himself had recorded in 1932………..” (Lyrics YT.)

In a mellow tone, Feeling fancy free, And I'm not alone, I've got company,
Everything's OK, The live long day, With this mellow song, I can't go wrong
In a mellow tone, That's the way to live…….

Thanks again for sharing. Enjoyed it   

Best wishes,
