1.   Finger-in-Ear.
A term employed by lazy journalists (usually in conjunction with the phrase 'woolly sweaters') to describe any activity within the folk scene over the last fifty years. Also used by a few folk club organisers who don't enjoy traditional songs to rebuff performers who sing them (as in: "We don't go for that finger-in-the-ear stuff at our club"). A stereotype possibly to be blamed on MacColl imitators who adopted the head-back, eyes shut posture, as well as the hand over the ear. However, I can't say I've seen one of those in a folk club for twenty years or more.

2. 2.   97 verse ballads.
A term used by people with a short attention span to describe any traditional song over four verses long. Alternatively, a bad performance of a five-verse ballad.

3.   Folk police.
People who care about the meaning of words.

Incidentally, Jim, I'm not sure who you're referring to as the 'folk establishment', but around the folk clubs I visit an awful lot of the floor performers sing unaccompanied, whether the song is traditional or not.

'Folk Taleban' - that's a new one. I must buy myself a turban.
