I used to be Jack Mostly Folk. I got that from a co-worker some years back. He asked me what kind of music did I play and sing and I answered'"mostly folk". He then said Oh. Jack "Mostly Folk" Roberts.I used that for about 8 years. Jack Mostly Folk was just to much, so some time back I decided to go with Mudjack and it's easier to type in. My given name is Jackie, but like Joe said you can't keep a little kiddies name ad I've been Jack for most of my adult life.
