I was surfing Gb stuff today and found this site with a picture of The GBS and Dana on the cover of the Rolling Stone, and Dans wearing a leather flight jacket with a GBII patch on the left breast. He's wearing it over his grey flightsuit. I dunno if it was originally part of his costume or what, but I just thought I'd share that. He're the link to them pic. Hope you enjoy.
