Deacon+ I'm not sure of musician availability these days since I am just an occasional tourist since my 3+ years living in BZ in the early 90's.
Talk to Charlie at Estelle's or Caesar at Orange gift shop, they should know any players around those parts. Ebbe, up at Sundiver/ Mata Grande studio also knows a bunch of pickers. Once again, good luck to your dad and tell him to keep on jammin.
