A battling musician realizes he's the sole man or woman on this planet who can bear in mind The Beatles immediately after waking up within an alternate reality in which they never ever existed.
So there is leakage there. Then I claimed I'd do a string quartet. The musicians objected to fiddling with headphones, so I gave them Paul's voice and guitar on two speakers either aspect in their microphones. So there is leakage of Paul's guitar and voice about the string tracks.
Soon after recovering, he sings the Beatles track "Yesterday" for his close friends and discovers they more info have not heard about the Beatles.
