BK,
On the LP 'Down Under' which is listed as Bootleg on Bogle's homepage though it easily could be bought in Germany from Autograph Records, a small German Folk label. It is a very good LP by the then young Eric Bogle, just singing and acompanying himself on the guitar. I have copied below the tracklist from the Bogle homepage, so you can see that Bogle is singing on the backside of that LP songs that are not from him (three of them, e.g., from Robertson). And he does a great job.
