Denny Docherty never got over his un requited love affair with Michelle Phillips, and hit the booze, which harmed his voice. Cass Elliot never got over her love affair with Denny, but as we know never lost her talents right up to the end. In all of that crowd which included John Sebastian and Barry Maguire, I could never figure out what Michelle Philips offered vocally. I thought Barry Maguire was a terrible singer, but seemed a very nice man. For me, for pure vocal ability in that era the Mamas and the Papas still hold the record. Michelle was replaced briefly and the band said they just did not have the right sound, so she must have had something. I'm not sure we've seen anything to beat them in that style of performance, however I'm open to suggestions and will look forward to listening.
