  We discuss the extended Nambu-Jona-Lasinio model as a low energy expansion,
all two-point functions and an example of a three-point function to all orders
in momenta and quark masses. The model is treated at leading level in $1/N_c$
but otherwise exact. Some comments about the QCD flavour anomaly and Vector
Meson Dominance in this class of models is made. Uses epsf.sty and rotate.sty.
One postscript figure included at the end.
