Chance encounter

In 1984, my friend - Kenny Mundie - and I were colleagues who worked night shift. One afternoon, Kenny picked me up and we drove into town. As we drove, Kenny mentioned a friend of his called Abbie Copeland whom he was convinced I must know. I said I didn't know Abbie, but I mentioned that I had heard of him from a friend of mine called Mike Geddes. Kenny said that he didn't know Mike, but I was adamant that he must know Mike. We were still debating the matter when we stopped behind a Ford Transit van at a set of traffic lights. As we waited for the lights to turn green, I looked to my left and Mike Geddes walked into view. I pointed towards Mike and said to Kenny, "That's Mike Geddes!" Before I could attract Mike's attention, he walked up to the van in front of us, opened the passenger door and climbed into the passenger seat. The van driver turned to greet Mike, giving both of us a clear view of his face for the first time. Kenny pointed at the van driver and exclaimed, "And that's Abbie Copeland!" I would love to know what the odds are of this chance encounter.
