The song is from Brendan Behan's play "The Hostage", yes?

If you want an alternative version, as a student a bunch of us wrote tunes to the lyrics to put on the play (we couldn't find the actual tunes - looking back I guess we didn't really know how to look and didn't try too hard!). One of the tunes we wrote were to the lyrics of "Open the Door Softly".

If you're interested, I'd be happy to oblige (it's been sitting in a cupboard for some years!)
