Abstract
The BRST quantisation of the Drinfeld - Sokolov reduction is exploited to recover all singular vectors of the Virasoro algebra Verma modules from the corresponding ones. The two types of singular vectors are shown to be identical modulo terms trivial in the cohomology. The main tool is a quantum version of the DS gauge transformation.
