I can't tell the difference between 3/4 and 6/8. A slip jig is in 9/8 and I do recognise that when I hear it, but that's because of the way the emphasised beats fall.
But what seems to be happening here, to my uncouth and uneducated ear, is that the percussion starts playing something else as the piece goes on, and there's a sort of ambiguity that arises.
But it may be illusory. I spent some time trying to plot out what the Beatles were doing in "Good Day Sunshine". The intro sounds like they're tossing a salad of 3s, 2s and 5s, but it's actually all in 4.
Another way of looking at it, is that the piece is in a simple 2/4 time with two sets of triplets per bar. The basic beat is very simple. Some percussion instruments are playing across the beat at times making the arrangement sound more complex than it is.
