Some good points are made in this article. One of the most striking for me is the fact that the Beatles did stop touring when they started recording "arty" more complex music and yet the Moodies maintained a grueling tour schedule throughout their extremely productive core 7 years. The Beatles never had to attempt reproducing "Strawberry Fields Forever" on stage whereas the Moodies were able to pull off  live performances of some of the most complex music in pop history! It's pretty amazing when you think about it. No wonder we love this band so much!
