The problem is anybody who is not ignorant of the works of the great Leonard Cohen will automatically think of the original lyrics, which, while brilliant, are out of place in this setting.
As for Song of Songs, it would be inappropriate to sing a song based on those in this situation also. Not everything Biblical is appropriate for singing in church. It's not that difficult a concept to grasp.
I didn’t propose that singing either Cohen’s lyrics or the Song of Songs in Church is appropriate.
