The album closes with a brief, frenetic version of Irving Berlin's "Russian Lullaby". Producer Bob Weinstock relates Coltrane's humorous interpretation:
We were doing a session and we were hung for a tune and I said, "Trane, why don't you think up some old standard?" He said, "OK I got it.["]...and they played "Russian Lullaby" at a real fast tempo. At the end I asked, "Trane, what was the name of that tune?" And he said, "Rushin' Lullaby." I cracked up.
Soultrane takes its title from a song on a 1956 album by Tadd Dameron featuring Coltrane, Mating Call. "Soultrane" does not appear on this Soultrane, and none of the five tunes on Soultrane are originals by Coltrane. The song "Theme for Ernie" was featured on the soundtrack for the 2005 film Hollywoodland.
