search for 2 headers and a body

Hey folks, I'd like to do something with procmail not at all related to spam  
or smartlist!

I want to search for a From line, a Subject line, and the first line of the 
body.

From:(_dot_)*someone(_at_)somewhere\(_dot_)com
Subject: Subject

begin 644 file.tar.gz

How can I search for them, in the above order (Check From line, then Subject  
line, then body scan) and if they all match I want to send the body of the  
message to a special program via pipe.

I was going to do this

:0
* ^From:(_dot_)*someone(_at_)somewhere\(_dot_)com
* ^Subject: Subject
{
        :0 B
        * begin 644 file.tar.gz
        {
        
                # should this be
                # :0fb
                # rather than what it is?
                # I just want the body
                # sent to the program
                :0
                | /path/to/my/program
        }
}


the problem is that
        1) it seems inefficient
        2) it's ugly
        3) it sends the headers to 'program' (do I use 'fb'?)

Thanks for any improvements you can make.
