%X We present a first test of heavy quark spin-flavour symmetries in matrix elements for semi-leptonic decays \bar B to D l\bar\nu and \bar B to D^* l\bar\nu. We show that O(1/m_Q) corrections are small at masses around the charm for form factors protected by Luke's Theorem, but are of order 30-40 \% for h_V and h_V/h_{A_{1}}.
