What are the "Revolving door" positions in notable groups?

In many groups that have managed to endure long periods of time, a core group of founders usually remains intact while other positions may turn over quite a bit. What are some good examples of positions within groups that are notoriously prone to turnover? The only caveat is that examples of this phenomenon o should only include full band members, and not sidemen who are not considered permanent members.

To get things going, here's a few I can think of:

Vocalist, Deep Purple: Although only four different men have sung for this group, there have been 6 different terms of someone serving as lead vocalist, including three by Ian Gillan.

Drummer, Black Sabbath: 8 different drummers have been band members, not including Brad Wilk. These 8 guys have served 19(!) terms, due to some drummers leaving then returning.

Drummer, the Cult: 11 drummers have played with this group. However, I'm suspicious that this is really a "sideman" position at this point.

So, what are some other examples of revolving doors in groups?

 

Yes - keyboards, lately it's been lead singers as well
Jethro Tull - Drummers, bassists, keyboardists

 

I'll add to the above by stating that if a group has a separate Wikipedia page to list all its members, the group probably suffers from revolving door syndrome.

 

Lead singer - Van Halen

Drummer - Spinal Tap

 

King Crimson: Everybody except Robert Fripp
Iced Earth: Everybody except Jon Schaffer

 

Drive-By Truckers have had quite a few bass players over the years

Adam Howell ('96-'97)
Chuck Bradburn ('98)
Rob Malone ('98-'99)
Earl Hicks (2000-2003)
Shonna Tucker (2003-2011)
David Barbe (Emergency fill-in, 12/2011-3/2012)
Matt Patton (2012-)

 

Yes, Keyboards: 7 individuals holding 14 terms (5 terms for Wakeman)--good one!

 

Roxy Music also went through ten different bassists over the course of their lifetime.

 

Rolling Stones second guitarist? Crowded house drummer.

 

The Fall.

 

Judas Priest has had several drummers.

 

I was thinking of both the Fall and Guided by Voices when I was making the OP. In both cases, the frontman eventually emerged as the band boss, diminishing the group concept, so I'm not sure how to handle those.

 

E Street Band guitarist.

 

Sweet. The most confusing and ever changing band I know. Wiki does a good job at explaining.
