The sheet music for ON THE GOOD SHIP "YACKI HICKI DOO LA" can be seen at the web site of The National Library of Australia.

Lyrics are identical to those that Joe posted above EXCEPT "Yacki Hicki Doo La" is in quotation marks and spelled without hyphens; and it has "——" in place of "hell".

...which makes me wonder: How did singers handle words like "hell" in those days? If "hell" couldn't be printed (although, obviously, it could be implied), did that mean it couldn't be sung? Did they sing "hell" or did they pause and be silent for one beat? I suppose it depends on the singer and the venue. But does anyone know for sure?
