Determining EVERY month between 2 given dates

Hi everyone, I have a table with the following data upon which I would
like to report:

SomeDt SomeValue
1-sep-09 100
12-dec-09 200
02-feb10 50
14-apr-10 75

I need to report on this data showing values for all months within the
given min and max dates on the file so:
These dates need to be part of a *rolling* report.

I have data for Sep, Dec,Feb and Apr, but I want to display on the
report ALL months regardless of whether they have data in the table
and return 0 where they do not. Thus:

Month Value
Sep 09 100
Oct 09 0
Nov 09 0
Dec 09 200
Jan 10 0
Feb 10 50
Mar 10 0
Apr 10 75


I can get the min and max and the count of months easily enough:

select min(SomeDt) as StDt, max(SomeDt) as EndDt, datediff("m" , StDt,
EndDt) as CountofMonthsBetween from SomeTable

What I cannot get is how to then determine what the months are in
between. What I want if possible is a resultset that looks something
like this

StDt EndDt Mth
01/9/09 14/4/10 Sep 09
01/9/09 14/4/10 Oct 09
01/9/09 14/4/10 Nov 09
01/9/09 14/4/10 Dec 09
01/9/09 14/4/10 Jan 10
01/9/09 14/4/10 Feb 10
01/9/09 14/4/10 Mar 10
01/9/09 14/4/10 Apr 10

How can I do it?

As much as possible I want to use QUERY resultsets, rather than
creating intermediary tables etc which are just messy in MS Access,
but will use them if no other choice.

Happy to write a function if needs be to calc the Mth column. Am
absolutely desperate so all help greatly appreciated. If it can't be
done at all via queries alone, please let me know this too.
