Picture of an Everly Brothers guitar on another thread (it was designed that way to produce a "dry", somewhat muted tone) got me wondering if there was anything on line about their father, legendary guitar picker Ike Everly. The answer seems to be "not a whole lot", but here is a recording of him with Phil and Don at Newport, long ago.
