We revisit the determination of the two-loop spectral function in the shear channel of hot Yang-Mills theory. Correcting a technical error in an earlier computation is seen to improve the infrared behavior of the quantity significantly, while a partial Hard Thermal Loop resummation is seen to have only a very minor numerical effect on the result. These facts make it possible to straightforwardly apply the spectral function to the corresponding imaginary time correlator and the shear sum rule
