If you could create a rock supergroup, who would be in it?

I saw this little exercise in Spin magazine back in fall of '04 (props if you can find it in an archive). The basic premise is to create a supergroup of your favorite musicians from the past and present, and describe what kind of sound you'd like to hear from the group and what sort of dynamic you think they'd likely have.

There are a few allowances and rules:

1) you can use people from past and present, and they can be dead or alive

2) the people you choose must be able to work together as a cohesive band. even if you love them all, you wouldn't put prince, jamiroquai, and michael jackson in the same band because they would clash personally, they would all kind of serve the same purpose, and the band just wouldn't work.

3) it's not concrete, but it's encouraged to at least pick a guitarist, a bassist, a drummer, and a singer, and you can add onto that as necessitated by your conceptual design.

4) please don't be unimaginative and say something like "led zeppelin is my supergroup" or "the who with david gilmour instead of pete townsend." the idea is to create an original concept/sound.

So, I'm curious as to who everyone in the community would choose for their supergroup, and can you describe how they would sound and how they would work together to create your perfect band. I'll tell you mine to start off:

Guitar: John McLaughlin (Mahavishnu Orchestra)

Bass: Les Claypool (Primus)

Drums: Thomas Pridgen (Mars Volta)

Vocals: Jon Anderson (Yes)

Keys: Herbie Hancock

Production/Songwriting/Sound effects/Guitar: Omar Rodriguez-Lopez (Mars Volta)

So I imagine this as a largely instrumental group, a combination of prog sensibilities (long songs, focus on the album as an art form, space/fantasy concepts) and a hard funk-fusion sound akin to the song Vital Transformation by the Mahavishnu Orchestra and the bass-heave rock-out parts of a lot of Yes songs.

I feel Geddy Lee would be more appropriate than Jon Anderson if this were the only style we're going after, but I think he'd bring a certain softness and sense of dynamics that would work against the raw funk of Pridgen and Claypool.

I think all these guys are still alive so there is hope. Descrbie the concept of your band too.
