(Bruce Walton) I saw YESTERDAY this evening, and I LOVED it. It reminds me of the people (more than one) who claim that there is a parallel timeline/worldline (Not one where the Beatles never became famous - like the world/time-line depicted in the movie "YESTERDAY") where the Beatles are still singing and John Lennon was never murdered. In fact, so the story goes, one man was propelled into this alternate timeline after experiencing an accident (sound familiar?) and learned that in this timeline the Beatles were still alive and performing together. He smuggled an album on cassette tape back into THIS timeline after he was shown the way back by a mysterious man from the other time-dimension. The album is called EVERYDAY CHEMISTRY ( see: LINK-1 ). More websites confirming this strange story: LINK-2 ... LINK-3 ... LINK-4 ... LINK-5 ... LINK-6 ... & LINK-7 ... Temporally Yours... Bruce. One more thing... Quantum Physics DOES IN FACT open up the possibiity of parallel dimensions-worldlines-timelines-realities in a Multiverse, symbolized by a tree with many branches (MULTI) but only one trunk (VERSE).
