We do have several search engines onsite, which are really quite useful. I particularly recommend the "Digitrad and Forum Search"; a search for redwing will get you some results, but red wing (the song's title) will get you more; including, in the DT:
RED WING (2) (parody)
RED WING (3) (parody)
CHARLIE CHAPLIN (parody)
And in the Forum, where people have asked for this song a number of times in the past:
Lyr Req: Little Redwing / Union Maid
A similar search for leprosy will find (among other things):
Jalousie or Jelosy HER ARM FELL OFF!!!
