Group/band members succeeding as solo acts

Is that rare? I wonder why we don't see this more often. Also, I'm not talking about guys who leave bands and make good music. I'm talking commercial success. You may like Joe Perry but no one gives a fuck.

That shit doesn't happen a lot, it seems.

Only guys I can think of:

Eric Clapton
John Lennon
Paul McCartney
Phil Collins
Peter Gabriel
George Michael

Who else?
