Jean asked the question above and I was wondering about the same thing - haven't found an answer on the ASCAP, BMI or SESAC sites or gotten a reply to my e-mails:

If you have a license from one, do you still need the others?

From what I can tell in the licensing agreements that are available on their sites - the answer would be YES. The agreement is a license only for the songs in the individual PRO's repertory (I thought the word was repertoire - but thats how its spelled on BMI and SESAC).

I'll weigh in on agreeing that songwriters should be paid for performance of their work.

I'll also weigh in on believing that the current system used by the PRO's doesn't do that outside of Radio/TV/motion picture royalties.
