Recently I've heard a song by The Irish Brigades titled Hands Up! Trousers Down! (or Hang On To Your Trousers) and now I'm looking for the lyrics. Google did not produce any good results, so you guys are my last change.
Some random lines I think(!) I remember are:

"Hang on to your trousers you can hear the Gardai(?) say
With a padlock on your bracelet (or brassard?) boy we think he's(?) on his way"

"Put on your thermal underwear and you will be ok"

"Sad news came from County Clare upon Saint Patrick's Day
(..) they took our man away"

Thanks
