“Who Needs It” as a composition is pretty minimal, which is the case with most of Lacy’s tunes. The form is AAAB. And the A section is 10 bars in length and in the key of Gb major, and the B section is 12 bars in length, in the key of G major. Simply put, it's the same theme played in two different keys. Comparable modal jazz tunes composed using this approach is the Miles Davis tune "So What," and John Coltrane's "Impressions." The difference, of course, is that Lacy's tune is in a major tonality, while the two aforementioned are in a minor key. (Please see lead sheet below)

You won’t be disappointed!
REVISION: After I posted this originally, soprano saxophonist Stefano Scippa informed me that he transcribed "Who Needs It" some time ago, and was generous enough to let me post it. FYI, this is a Bb part, in the key of the soprano. Thanks, Stefano!
