I just found this clip which shows parts of the rehearsal for the Hall Of Fame induction concert of a.o. CCR in 1993. Of course Fogerty didn't wanna play with the surviving members Stu Cook and Doug Clifford so he used an all star band, including Bruce Springsteen, Robbie Robertson and Don Was. when they got to work on "Proud Mary" you can hear shortly Was telling Fogerty about the version he just recorded with Brian.
