The album also included several Mack vocals, done primarily in the country-esque blues/gospel style for which he became well-known.

Regarding the vocals on this album, music critic Bill Millar said: "For consistency and depth of feeling – the best blue-eyed soul is defined by Lonnie Mack's ballads and virtually everything the Righteous Brothers recorded...Lonnie Mack wailed a soul ballad as gutsily as any black gospel singer.

The anguished inflections which stamped his best songs had a directness which would have been wholly embarrassing in the hands of almost any other white vocalist.

[9] An expanded version of the album, incorporating the original cover art, was released in 1969 by Elektra Records under the title "For Collectors Only".

It adds two 1964 tracks ("Farther on Down the Road" and "Chicken Pickin'") to those on the original release.
