Roger's reply sits just perfect from where I stand, polite with a decent explanation. You could also throw in Jethro Tull & many other rock bands that had a blues or folk tilt in their start but they are very accessable on rock sites as well as there own. Folk casts a wide net, some perfer a tigher & smaller net, others light a larger one that would encompass more, but to encompass all & allow overfishing would deplete our resources. Sorry for the analogy. (Thank you Roger) Barry
