| Number Ones - May 1943There are a number of reasons why there can be debate about 
which record should be considered to have been "Number One" 
in a particular country on a certain date.  These are discussed further down 
this page.  However there is clearly a sizable group that don't want 
to know about these details and just want to know what record was top of the 
charts on a given date (such as their birthday).  This table shows which records 
were number one for various countries over the month of May 1943.

 M |  | Country |  As was mentioned above, there are all sorts of reasons why 
the entries here rather over simplify the real situation.  We have made a large 
number of sweeping assumptions in order to present a simple picture to the vast 
number of users that just want a song title.  This means that there are a number 
of entries in these tables that should be handled with caution.  In addition where 
these entries differ from the original sources (listed later) it should be assumed 
that the sources are correct, where these entries conflict with the main data 
assume that the other data is correct, if you find either of these cases please 
tell us and we'll correct the data here.
 
If, like us, you are the type of person that wants to know if a song was top of the 
Jukebox or Jockeys chart, or where a double-A side was released, or when chart 
entries did not specify an artist, or when the charts switched from one magazine 
to another we suggest that you have a look at the original sources: |

#3 - Kate Smith & Bing Crosby
I can find no record of this being a duet. Am pretty sure both Bing Crosby & Kate Smith had solo recordings of this.
That looks likely. We've assumed that they shared the Australian number 1 slot, giving 2 months to each. thanks
