The worldsheet string theory dual to free 4d ${\cal N}=4$ super Yang-Millstheory was recently proposed in arXiv:2104.08263. It is described by a freefield sigma model on the twistor space of ${\rm AdS}_5\times {\rm S}^5$, and isa direct generalisation of the corresponding model for tensionless stringtheory on ${\rm AdS}_3\times {\rm S}^3$. As in the case of ${\rm AdS}_3$, theworldsheet theory contains spectrally flowed representations. We proposed inarXiv:2104.08263 that in each such sector only a finite set of generalised zeromodes (`wedge modes') are physical. Here we show that after imposing theappropriate residual gauge conditions, this worldsheet description reproducesprecisely the spectrum of the planar gauge theory. More specifically, thestates in the sector with $w$ units of spectral flow match with single traceoperators built out of $w$ super Yang-Mills fields (`letters'). The resultingphysical picture is a covariant version of the BMN light-cone string, now witha finite number of twistorial string bit constituents of an essentiallytopological worldsheet.
