Martyn Wyndham-Read has recorded quite a number of Lawson songs, including 'Andy's gone with cattle', which he put on four different LPs, one of which, Emu Plains, has been re-released on CD. He has also produced 'Down the Lawson Track', which has been performed at various venues, including the Royal Festival Hall, and Canberra, where it was recorded by ABC on 8/04/09 and subsequently broadcast. I don't know if it's still available, but if anyone wants to PM me I can give them more details.
