Given their phenomenal output, and their huge chart success, it's no surprise that this second volume proves every bit as rich as the first. John, Paul, George, and Ringo had that rare chemistry that moved musical mountains, with more great songs than many people have had hot dinners, and they're still affecting the course of popular music. Thirty years later, all the paths they hinted at have yet to be explored, which is about as high a testament as can be given. --Chris Nickson
