I watched a special about them recently. They were, and are, an amazing band, especially when you realize they had the best drummer (Keith Moon), best bass player (John Entwistle), and one of the best guitarists in Rock history (Townsend). Roger is one heck of a fine singer, too.
In terms of music quality, they are probably the 2nd best all around "rock" band of all time.
Watch their 1970 concert at the Isle of Wight, just amazing. Still get a kick out of Ox’s skeleton outfit....just watching Moonie alone was worth the price of admission.
