I include quite a few Dylan songs in my repertoire, but I don't try to sound just like Bob, and (although I am greatly influenced by his phrasing and other aspects of his vocal performance) I'm quite sure that I sound very different.

Back in the 60s/70s, there were always guys with harmonicas in racks who were interested only in sounding as much like Dylan as humanly possible, and often succeeding. The best among them earned my repect for their skill, while the less-competent simply bored me (although I've always enjoyed hearing most of the songs, even when served up in the least imaginative interpretations).

No offence, George. I assume you were one of those guys, and probably one of the best.
