This must have been about 10-15 or so years ago. . . .
Friends of ours from NJ moved out to Minnesota and their new hall at the time was Prince's hall (this was just around (maybe slightly before) the time he started in the cult).
From what I recall, they said Larry Graham was a MS and -- according to these folks -- a really nice, down to earth guy.
Prince, however, was weird.
Again according to them, he would come into the meeting just as it started and sit down right in the front row with a small entourage. After the meeting, he did not mingle with the congregation, but talked only to Graham and a few select bros. He would then quickly leave without making any eye contact with the rest of publishers.
