On March 7, 1963, Coltrane and Hartman had decided on 10 songs for the record album, but en route to the studio they heard Nat King Cole on the radio performing "Lush Life", and Hartman immediately decided that song had to be included in their album.

[10] Jazz writer Michael Cuscuna explains the speculation of two different versions of the album: "At a later date, Coltrane decided to overdub some additional obbligato saxophone phrases behind Hartman's vocals on 'My One and Only Love', 'Lush Life' and 'You Are Too Beautiful'.

"[12] In 2005, the raw tapes were reviewed by jazz archivist Barry Kernfeld, who documented there were actually complete alternate takes for all six songs that he considered "absolutely riveting.

"[13] Until clear ownership of these tapes is established between the Coltrane family and Universal Music, there are no plans for their release.

It has become a classic ballad jazz album, and the renditions of "Lush Life", "My One and Only Love", and "They Say It's Wonderful" are considered definitive.
