It really is. From Rubber Soul onwards, the Beatles were strictly a studio band. They had to figure out how to do on stage what the Beatles did with a full studio. They have more musicians and modern technology, but Revolution #9 is challenging, and they make Tomorrow Never Knows an absolute banger live. Plus they play everything without breaks. They do rotate musicians, so individuals can sit out a few songs to eat and pee, but they keep going for 13 hours solid.
