The generic googly amplitudes in gauge theory are computed by using theCachazo-Svrcek-Witten approach to perturbative calculation in gauge theory andthe results are in agreement with the previously well-known ones. Within thisapproach we also discuss the parity transformation, charge conjugation and thedual Ward identity. We also extend this calculation to include fermions and thegoogly amplitudes with a single quark-anti-quark pair are obtained correctlyfrom fermionic MHV vertices. At the end we briefly discuss the possibleextension of this approach to gravity.Comment: Latex file, 38 pages, 15 figures; v2, minor changes, references added; v2, minor changes, 2 references adde
