I've always been very curious to hear the demo's for communique. Wasn't there a quote from either Barry Beckett or Jerry Wexler after hearing the demo's along the lines of 'we just have to re-record it just like that over here'?
Taking the line that they played most songs live first, which is good angle to come from, this would leave In My Car and Bernadette as possible contenders for out take songs.I think more likely though are that the acetates are preliminary mixes of the recorded tracks we already know. Studio time and tape was expensive back then, especially premium studios such as Nassau, I doubt they would record things that were not perfected to a level.
