Conversation so far:
Whose idea was it to form R.E.M.?
The quartet agreed to collaborate on several songs; Stipe later commented that "there was never any grand plan behind any of it".
Who were the original members?
Stipe and Buck then met fellow University of Georgia students Mike Mills and Bill Berry.

Question: Did they add anyone else?
Self-contained rewrite: Did the band R.E.M. add anyone else other than Mike Mills and Bill Berry?
