Well, last time I looked, which was a few seconds ago:

     August 13, 1982              - 17 -                      RFC #822


 
     Standard for ARPA Internet Text Messages


                        ";"    date-time         ; time received

     originator  =   authentic                   ; authenticated addr
                   [ "Reply-To"   ":" 1#address] )

     authentic   =   "From"       ":"   mailbox  ; Single author
                 / ( "Sender"     ":"   mailbox  ; Actual submittor
                     "From"       ":" 1#mailbox) ; Multiple authors
                                                 ;  or not sender

...

     4.4.1.  FROM / RESENT-FROM

        This field contains the identity of the person(s)  who  wished
        this  message to be sent.  The message-creation process should
        default this field  to  be  a  single,  authenticated  machine
        address,  indicating  the  AGENT  (person,  system or process)
        entering the message.  If this is not done, the "Sender" field
        MUST  be  present.  If the "From" field IS defaulted this way,
        the "Sender" field is  optional  and  is  redundant  with  the
        "From"  field.   In  all  cases, addresses in the "From" field
        must be machine-usable (addr-specs) and may not contain  named
        lists (groups).

so you *can* have multiple authors in a "From:" line.

However, if the intent is to indicate that the sender was "George Bush",
with the address "bush@tree", it is correct that

>It should be George Bush <bush@tree>.

and, furthermore (as explained in the description of the "n#item"
metasyntax,

>Even in the context of a To: line, where multiple addresses are fine,
>that line is illegal. If it represents three differrent addresses,
>the addresses should be seperated by commas.

so if you really *were* saying the message was from "George", "Bush",
and "bush@tree", the From: line should read

	From: George, Bush, bush@tree
