Of course they do and likewise, old folk musicians could do with shearching out a fiew new/fresh ideas too.
There have been a host of new bands that have come - and gone - over the last ten, twenty, thirty years. Musical performance has moved on at an astonishing pace but then so has the quality and availability of the tools of the trade, fiddles, pipes, guitars and ampllifying equipment and a sizeable increase in festival numbers, touring venues and recording possibilites. The down turn of course is that true singers are rarely to be heard along side these musicians. Singers often become the recognisable "face" of a band, far far too much for many star musicians to take. cheers.
