Actually "Camptown Races" shouldn't really be in this list as I have never sung it in public. Whilst in the "Idle Fellows" I always gave a somewhat lack-lustre performance on my penny-whistle of which I was never terribly proud. On the other hand Wilfried Drygala gave this number a considerable thrashing on his banjo and he was ably backed by Bernd Gerken and Brian Kelly.
The "Camptown Races" that I try to "sing" can be found in Lieder, Songs und Gospels 3.
