The quark generalised parton distributions of the pion are calculated from
lightcone wavefunctions in transverse lattice gauge theory at large N_c. The
pion effective size is found to decrease with increasing momentum transfer. An
analytic ansatz, consistent with finite boundstate lightcone energy conditions,
is given for the lightcone momentum dependence of the wavefunctions. This leads
to simple, universal predictions for the behaviour of the distributions near
the endpoints, complementing numerical DLCQ data.Comment: 9 pages, invited talk at Light-Cone 2004, Amsterdam, 16-20 August,
