Nice addition! There is some awesome cow bell throughout the song.
The intro with the electric guitar and drums feels like something they took from the cutting room floor after they recorded Rubber Soul, leading to the insanity of the main verse.
It’s one of those songs that feels like Lennon wrote the crazy verse and McCartney wrote a more melodic chorus and they rammed to two pieces together.
Finally, those last 30 seconds are a really cool mixture of cow bell, a great bass riff, electric and then psychaedelic guitar and the boys jabbering “come on.”
