Mr. Venn is at it again

Wow, I haven't posted in a while.

Jon Anderson is the singer of Yes.
Ian Anderson is the flautist/singer of Jethro Tull.
Ian Gillan is the singer of Deep Purple.
I think a Venn diagram is in order here.

We need Jon Gillan, the progressive rock flautist. He doesn't sing.
Really, you could say "Anderson (or Jon or Gillan) means singer, Ian means flute player," but that would make Ian Gillan only a flautist. He's only a singer. So if neither Ian nor Anderson is present in the name, it means flautist. Jon Gillan switched logical places with Ian Gillan.
Remember, Ian=flute, Jon/Gillan-singer.

I want Tim Storms as the singer for my band.
