[Chris the Chees]

Vocals & Guitar - James Dean Bradfield (Manic Street Preachers)
Lead Guitar - Steven Wilson (Porcupine Tree)
Vocals - Cerys Matthews (Catatonia)
Bass - Kim Deal (Pixies)
Percussion - Jimmy Chamberlain (Smashing Pumpkins)

And lyrics by a collection of contributing artists.

I doubt many here have heard of my two choices for vocals, but James Dean Bradfield (Manic Street Preachers) is one of the best vocalists to have graced rock music. The only other two male singers who come close as Maynard Keenan (Tool) and Jarvis Cocker (Pulp). I also had to include either Cerys Matthews (Catatonia) or Dolores O'Riordan (The Cranberries), because they have truly beautiful voices, Cerys wins out because I happen to be going through a Catatonia patch at the moment.

But in reality the ultime super group already exists: -

James Dean Bradfield - Vocals & Guitar
Nicky Wire - Bass & Lyrics
Sean Moore - Drums

And formerly

Richie Edwards - Guitar & Lyrics
