The holographic dual of large-N-c super-Yang-Mills coupled to a small number of flavours of fundamental matter, N-f << N-c, is described by N-f probe D7-branes in the gravitational background of N-c black D3-branes. This system undergoes a first order phase transition characterised by the 'melting' of the mesons. We study the high temperature phase in which the D7-branes extend through the black hole horizon. In this phase, we compute the spectral function for vector, scalar and pseudoscalar modes on the D7-brane probe. We also compute the diffusion constant for the flavour currents.
