Using regex to remove info from _raw but still have full message as a field

I want to have both the first() of the _raw message and the same message without the time information I have regex that removes the time information from _raw right now but I lose it for good when I want to still have it as a different field

search terms  | eval TimeInHour=_time%3600 | rex mode=sed "s/ \d{4}-\d{1,2}-\d{1,2} \d{1,2}:\d{1,2}:\d{1,2}//g" | stats first(_raw) by punct,TimeInHour,_raw,_time |  stats count by _raw,TimeInHour,punct |  addinfo| eval hours = round((info_max_time - info_min_time)/3600,0) | where count > hours-1

So what I want would look like

    _raw                                               new_raw
    2013-08-12 16:32:58 ib0: tx_head 409, tx_tail 281  ib0: tx_head 409, tx_tail 281 
    2013-08-12 16:32:58 ib0: latency 27472681 msecs    ib0: latency 27472681 msecs
    2013-08-12 16:32:58 ib0: tx_head 555, tx_tail 427  ib0: tx_head 555, tx_tail 427
