Jack is between 70 and 75 according to the wife of my friend Michael. She called about some prints I was doing for her. Said Michael was branding calves today and would not be near a phone until late. One thing, when you meet Ramblin' Jack, you soon realize that he is called Ramblin' Jack not because he travels around alot, which he does, but because of the way he talks.
Ramblin' Jack learned guitar from Woody Guthrie, Arlo's Dad (This Land Is Your Land and etc). Taught Bob Dylan songs and helped teach him guitar. And mostly helped keep the folk tradition alive thru his music and performances. He is a legend in his own mind.
