Via FB group Jefferson Airplane: Come Up The Years and Bless it's Pointed Little Head: the Jack Casady appreciation society, a fellow Casady fan is reporting that this bass has been located and returned to Jack.
The deep brown finish was stripped, but the headstock inlay (by Margareta Kaukonen) and wood carving control plate (by Stanley "Bear" Owsley) give it away.
"Jack's 67 Guild Starfire bass is indeed back in Jack's arms ! It looks different as someone refinished it after it was stolen. It was stolen after a Jefferson Airplane show at the Seattle Center Coliseum October 11th, 1969. In 1979 my dear friend and bass player bought the guitar from a fellow employee. He had no idea of its history. January 5th this year, I saw a post that Jack had written and somebody shared. I took one look at that picture and said that's Leroy's bass ! I called him right away, and asked if he wanted me to contact Jack to get it back to him. Leroy paid $1800 for it in 1979. He said do it. So after a lot of chatting with people that knew Jack, I finally spoke with Jorma. We made a little funny plan , to surprise the hell out of jack. I'm not going to tell the whole story here, because I have written the story already. To wrap this up, I shipped Jack's bass to him about a month ago ! Jack is very happy !"
