Dick are you suggesting that top level guitar players like Paul Brady, Martin Simpson or Nick Jones at his best or a fiddle player of Tom Mconvilles calibre dumb down their performances so as not to embarrass us lesser mortals. The above artists are able to take a fairly ordinary song and turn it with their embellishments and instrumental interludes into a musical work of art simply because they can, you and I can only wish we could do the same. So yes the song is important. almost as important its presentation.
