Opera with Manos Hadjidakis
- "Following the release of God Bless in May 68, the Greek composer and songwriter Manos Hadjidakis [...] invited Mayo and Steve to New York for discussions about a possible project. Hadjidakis had played God Bless... to his associate the violinist Isaac Stern, who was also known for nurturing new talent" (source: God Bless 2011 booklet)
- "What the pair envisioned was a rock opera featuring Grace Slick in the lead role with the Red Krayola as the backing band. Why they figured Slick would consider leaving a successful career with the Jefferson Airplane for mainstream entertainment is a mystery. After the bizarre red herring there were few fresh opportunities for the duo and so they decided to go their separate ways."
