To be honest, it's a credit to Brian Epstein and George Martin that they survived as long as they did. Living in such close confinement for years, like some weird prison. Add into that all that creativity and passion it's amazing that it lasted so long and so much great stuff came out of it. The fact that they could put it all aside and produce something as wonderful as Abbey Road is just unbeliveable. The thing I love about Abbey Road is that the section posted here (which is fantastic btw) is like rapid fire number ones, any one of the snippit songs could easily be a huge Beatles hit.
