Speaking of merging songs - I have this weird thing going on in my head where Incy Wincy Spider turns into Ten Green Bottles halfway through, and I've Got a Lovely Bunch of Coconuts turns into the theme for Albert the Fifth Musketeer.

And yeah, I get that you were meaning that it's not just the Beatles that bring back memories. I was just aimlessly commenting that Penny Lane = Penny Crayon in my head. I get so many memory flashbacks from music every day - even down to non-event memories, like walking through a particular area of town while listening to a particular song.

And now I have the Penny Crayon theme stuck in my head. Fantastic.
