  Egge, Loehr and Warrington gave in \cite{ELW} a combinatorial formula that
permits to convert the expansion of a symmetric function, homogeneous of degree
$n$, in terms of Gessel's fundamental quasisymmetric functions into an
expansion in terms of Schur functions. Surprisingly the Egge, Loehr and
Warrington result may be shown to be simply equivalent to replacing the Gessel
fundamental by a Schur function indexed by the same composition. In this paper
we give a direct proof of the validity of this replacement. This interpretation
of the result in \cite{ELW} has already been successfully applied to Schur
positivity problems.
