VIDEO : How ?Yellow Submarine? Saved 'The Beatles'

Once upon a time ? or maybe twice ? there was a gloriously colorful and strange film called ?Yellow Submarine.? The 1968 cartoon helped usher The Beatles out of an odd, hectic period for the band and would serve as a gateway for subsequent generations of Beatles fans to come. When ?Yellow Submarine? was released in the summer of 1968, the Beatles were bigger than Jesus (or so John Lennon had famously said two years earlier, to plenty of criticism). But things had gotten a little rocky within the group.
