G'day Peace,

It's worth keeping in mind that a popular singer, as Slim was, inevitably has other people's songs "credited" to him. Two obvious examples in your list are:

The Pub With No Beer: © Gordon Parsons (even if he did pinch most of the words from Paddy Sheehan's 1941 poem A Pub Without Beer ... and the tune from the first part of Stephen Foster's Beautiful Dreamer!)

Gum Trees By The Roadway was the title of an earlier popular Australian song ... (~)'20/'30s. I'm not sure if Slim's rendition is his own - or a case of him reviving an old favourite.

Regards,

Bob
