Abstract
The Drell-Hearn-Gerasimov sum-rule is really two sum-rules: one for ea ch of the valence and the sea/glue contributions to the nucleon wavefu nction. The convergence of these sum-rules follows from the Froissart bound for spin dependent processes in QCD and is necessary for the con sistency of the constituent quark model of low energy QCD. Some challe nges for future polarised photoproduction experiments, for example at ELFE, are discussed.
