At the risk of raising the ire of Catspaw; Curly pow, unfortunately, does refer to a hairy region, further south than the forehead and the version which the original poster was referring to was by The Flying Column back in the early seventies.
Light Ragade, as I'm sure someone has by now pointed out is actually "Life Brigade".
It's a good wee song apart from the disguised reference to the hairy region. I would tend to explain that it means Hairy Chest if asked but so far, no-one has.
