While I knew Gabriel would win last round, I'm surprised there was such little love for Greg Lake. Well, maybe this faceoff between the other two founding fathers of prog rock will be closer. Neither Jethro Tull or The Moody Blues get a lot of discussion around here, but they are a couple of legends of 60s and 70s rock, and the engineers of the progressive genre... moreso than Yes or Genesis in my opinion. Both have a deep studio library, and are (from what I've heard) are beastly acts live.
While I prefer JT as a band, I'm gonna give the nod to Hayward here. He may have not held all the vocal duties, but he was the key voice behind MB's, and I'll take him.
