vertical brace in lyrics

[Susan G. Kleinmann]

Is there a way to insert a vertical curly brace in lyrics, in a case
where a group of stanzas has a common ending, e.g.:

    lyrics for one stanza         |
    lyrics for another stanza     |
    lyrics for yet another stanza |  common ending
    lyrics for yet another stanza |

                                  ^
   Big vertical brace goes here---| 

Optimally, 
-- the vertical brace would be long enough to span all (or at least
   a specified set of) preceding stanzas; and
-- the common ending could be vertically centered relative to the group
   of stanzas.

Thanks,
Susan
