I'm sure that the version Boab is/was looking for was a lullaby recorded by Bing Crosby in the 1930s.
It was a childhood favourite of my late brother, another Boab, and during the latter stages of his terminal illness around twenty years ago I spent quite some time on a fruitless search for a copy of the record or the sheet music.
The only line of it that I can recall is 'so go to sleep my little drummer boy'.
If anyone out there could come up with the complete issue I, too, should be most grateful.
Cheers,
