This is just simply another misheard lyric, this time care of Bill. Apparently, back in his younger days, he thought the chorus to Caribbean Queen by Billy Ocean was, “Gary Busey, now we’re sharing the same dream”. He just thought Billy Ocean had similar ideals and goals as Gary Busey. And while that may indeed be true (no one can know for sure), Billy’s actually singing about his Caribbean Queen. I wish I had more to add, but, well…there it is.
