this is the same group as on twinight, tad, CRA, Cash, mercury, etc. (obviously there were lineup changes). We talk about this record in the interview on my webpage. I don't understand your question, though, Clifford Curry, lead of the Notations was 100% Chicago. Maybe you are confusing him with the other singer Clifford Curry on Elf, who was not related in any way? Thanks.
