  We develop a new classical action that in addition to $\mathrm{MHV}$ vertices
contains also $\mathrm{N^kMHV}$ vertices, where $1\leq k \leq n-4$ with $n$ the
number of external legs. The lowest order vertex is the four-point MHV vertex
-- there is no three point vertex and thus the amplitude calculation involves
fewer vertices than in the CSW method and, obviously, considerably fewer than
in the standard Yang-Mills action. The action is obtained by a canonical
transformation of the Yang-Mills action in the light-cone gauge, where the
field transformations are based on the Wilson line functionals.
