Deletion of Jethro Tull

Comment: The disambiguation page could be eliminated if there was a clear  for the name, but I don't think that is the case here. Scientists and historians may enter "Jethro Tull" to find the agriculturalist, music fans may use the term to search for the band. Since the agriculturalist is clearly a notable historical figure, he may be just as "primary" as the famous band. The brief detour through the disambig page when someone searches for the name is a bit annoying but easily clicked through
