The Bilateral Vandermonde Convolution
The first method uses the fact that any generalized hypergeometric series can be expressed as a sum of two ordinary hypergeometric series. The second method uses the evaluation at the poles of an imaginary integral. And the third method uses the bilateral analogue of Dougall’s theorem.
