i had told gully i did n't like singing the really bawdy songs like `` the cuckoo 's nest '' and `` captain black 's courtship '' 'cause i did n't like the way the men looked at me when we did them-all smirks and knowin ' winks and such-and gully says that some men would look at me that way if i was up there in a white gown with wings and halo singin ' the bloody messiah , so leave off .
