Thanks, Freddy Headey, for pointing me in the direction of some enjoyable pieces. I get confused and a tad annoyed when people decry 'commercialisation' of 'folk revivals'. Take away any commercial element and you have more or less nothing left: no venues involving payment, no music lessons involving payment, no recordings involving payment (including paying for the equipment etc), no publishing of 'research' on web sites which at the end of the day are paid for not free. The three drunks in the bar were presumably drunk on beer they had paid for, in premises for which rent was paid.
