Perhaps a long shot here. Robert Fripp is the odd one - and not just because he is!

The others are multi-instrumentalists, Fripp sticks to what he knows best - guitar.

Then again, I guess you could also call the others the "frontman" to their groups, whereas Fripp doesn't sing. Not that Oldfield does... often, anyways.
